Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156770, here are decompositions:

  • 37 + 156733 = 156770
  • 43 + 156727 = 156770
  • 67 + 156703 = 156770
  • 79 + 156691 = 156770
  • 139 + 156631 = 156770
  • 151 + 156619 = 156770
  • 181 + 156589 = 156770
  • 193 + 156577 = 156770

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 156,770 and was likely granted around 1873.

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

Position in π

The digit sequence 156770 first appears in π at position 802,971 of the decimal expansion (the 802,971ordinal-suffix:st 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.
