Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179998, here are decompositions:

  • 17 + 179981 = 179998
  • 29 + 179969 = 179998
  • 41 + 179957 = 179998
  • 47 + 179951 = 179998
  • 59 + 179939 = 179998
  • 89 + 179909 = 179998
  • 101 + 179897 = 179998
  • 149 + 179849 = 179998

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 179,998 and was likely granted around 1875.

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

Position in π

The digit sequence 179998 first appears in π at position 2,947 of the decimal expansion (the 2,947ordinal-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.
