Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142706, here are decompositions:

  • 7 + 142699 = 142706
  • 97 + 142609 = 142706
  • 139 + 142567 = 142706
  • 163 + 142543 = 142706
  • 337 + 142369 = 142706
  • 349 + 142357 = 142706
  • 379 + 142327 = 142706
  • 409 + 142297 = 142706

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 142,706 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 142706 first appears in π at position 194,684 of the decimal expansion (the 194,684ordinal-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.
