Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178006, here are decompositions:

  • 5 + 178001 = 178006
  • 53 + 177953 = 178006
  • 89 + 177917 = 178006
  • 113 + 177893 = 178006
  • 167 + 177839 = 178006
  • 263 + 177743 = 178006
  • 359 + 177647 = 178006
  • 383 + 177623 = 178006

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 178,006 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 178006 first appears in π at position 395,650 of the decimal expansion (the 395,650ordinal-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.
