Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156370, here are decompositions:

  • 17 + 156353 = 156370
  • 23 + 156347 = 156370
  • 41 + 156329 = 156370
  • 101 + 156269 = 156370
  • 113 + 156257 = 156370
  • 239 + 156131 = 156370
  • 251 + 156119 = 156370
  • 281 + 156089 = 156370

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 156,370 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 156370 first appears in π at position 820,585 of the decimal expansion (the 820,585ordinal-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.
