Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130770, here are decompositions:

  • 41 + 130729 = 130770
  • 71 + 130699 = 130770
  • 83 + 130687 = 130770
  • 89 + 130681 = 130770
  • 113 + 130657 = 130770
  • 127 + 130643 = 130770
  • 131 + 130639 = 130770
  • 137 + 130633 = 130770

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 130,770 and was likely granted around 1872.

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

Position in π

The digit sequence 130770 first appears in π at position 336,477 of the decimal expansion (the 336,477ordinal-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.
