Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135830, here are decompositions:

  • 31 + 135799 = 135830
  • 43 + 135787 = 135830
  • 73 + 135757 = 135830
  • 103 + 135727 = 135830
  • 109 + 135721 = 135830
  • 181 + 135649 = 135830
  • 193 + 135637 = 135830
  • 223 + 135607 = 135830

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 135,830 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 135830 first appears in π at position 602,531 of the decimal expansion (the 602,531ordinal-suffix:st 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.
