Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151370, here are decompositions:

  • 13 + 151357 = 151370
  • 31 + 151339 = 151370
  • 67 + 151303 = 151370
  • 97 + 151273 = 151370
  • 127 + 151243 = 151370
  • 157 + 151213 = 151370
  • 181 + 151189 = 151370
  • 199 + 151171 = 151370

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 151,370 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 151370 first appears in π at position 16,049 of the decimal expansion (the 16,049ordinal-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.
