Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156418, here are decompositions:

  • 47 + 156371 = 156418
  • 71 + 156347 = 156418
  • 89 + 156329 = 156418
  • 149 + 156269 = 156418
  • 191 + 156227 = 156418
  • 347 + 156071 = 156418
  • 359 + 156059 = 156418
  • 557 + 155861 = 156418

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 156,418 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 156418 first appears in π at position 908,962 of the decimal expansion (the 908,962ordinal-suffix:nd 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.
