Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129852, here are decompositions:

  • 11 + 129841 = 129852
  • 59 + 129793 = 129852
  • 83 + 129769 = 129852
  • 89 + 129763 = 129852
  • 103 + 129749 = 129852
  • 181 + 129671 = 129852
  • 211 + 129641 = 129852
  • 223 + 129629 = 129852

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 129,852 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 129852 first appears in π at position 48,564 of the decimal expansion (the 48,564ordinal-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.
