Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130436, here are decompositions:

  • 13 + 130423 = 130436
  • 37 + 130399 = 130436
  • 67 + 130369 = 130436
  • 73 + 130363 = 130436
  • 157 + 130279 = 130436
  • 337 + 130099 = 130436
  • 349 + 130087 = 130436
  • 367 + 130069 = 130436

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 130,436 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 130436 first appears in π at position 389,006 of the decimal expansion (the 389,006ordinal-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.
