Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135786, here are decompositions:

  • 5 + 135781 = 135786
  • 29 + 135757 = 135786
  • 43 + 135743 = 135786
  • 59 + 135727 = 135786
  • 67 + 135719 = 135786
  • 89 + 135697 = 135786
  • 137 + 135649 = 135786
  • 139 + 135647 = 135786

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 135,786 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 135786 first appears in π at position 357,318 of the decimal expansion (the 357,318ordinal-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.
