Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162500, here are decompositions:

  • 7 + 162493 = 162500
  • 43 + 162457 = 162500
  • 61 + 162439 = 162500
  • 109 + 162391 = 162500
  • 157 + 162343 = 162500
  • 211 + 162289 = 162500
  • 223 + 162277 = 162500
  • 271 + 162229 = 162500

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 162,500 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 162500 first appears in π at position 150,159 of the decimal expansion (the 150,159ordinal-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.
