Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162200, here are decompositions:

  • 109 + 162091 = 162200
  • 193 + 162007 = 162200
  • 223 + 161977 = 162200
  • 229 + 161971 = 162200
  • 277 + 161923 = 162200
  • 331 + 161869 = 162200
  • 421 + 161779 = 162200
  • 439 + 161761 = 162200

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 162,200 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 162200 first appears in π at position 107,277 of the decimal expansion (the 107,277ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
