Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162154, here are decompositions:

  • 11 + 162143 = 162154
  • 101 + 162053 = 162154
  • 137 + 162017 = 162154
  • 197 + 161957 = 162154
  • 233 + 161921 = 162154
  • 281 + 161873 = 162154
  • 347 + 161807 = 162154
  • 383 + 161771 = 162154

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 162,154 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 162154 first appears in π at position 532,598 of the decimal expansion (the 532,598ordinal-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.
