Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167900, here are decompositions:

  • 13 + 167887 = 167900
  • 37 + 167863 = 167900
  • 223 + 167677 = 167900
  • 277 + 167623 = 167900
  • 307 + 167593 = 167900
  • 379 + 167521 = 167900
  • 409 + 167491 = 167900
  • 457 + 167443 = 167900

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 167,900 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 167900 first appears in π at position 339,800 of the decimal expansion (the 339,800ordinal-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.
