Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170988, here are decompositions:

  • 17 + 170971 = 170988
  • 31 + 170957 = 170988
  • 61 + 170927 = 170988
  • 67 + 170921 = 170988
  • 89 + 170899 = 170988
  • 101 + 170887 = 170988
  • 107 + 170881 = 170988
  • 131 + 170857 = 170988

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 170,988 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 170988 first appears in π at position 768,979 of the decimal expansion (the 768,979ordinal-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.
