Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 190642, here are decompositions:

  • 3 + 190639 = 190642
  • 29 + 190613 = 190642
  • 59 + 190583 = 190642
  • 113 + 190529 = 190642
  • 233 + 190409 = 190642
  • 239 + 190403 = 190642
  • 251 + 190391 = 190642
  • 311 + 190331 = 190642

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 190,642 and was likely granted around 1875.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 190642 first appears in π at position 293,970 of the decimal expansion (the 293,970ordinal-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.
