Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130242, here are decompositions:

  • 19 + 130223 = 130242
  • 31 + 130211 = 130242
  • 41 + 130201 = 130242
  • 43 + 130199 = 130242
  • 59 + 130183 = 130242
  • 71 + 130171 = 130242
  • 163 + 130079 = 130242
  • 173 + 130069 = 130242

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 130,242 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 130242 first appears in π at position 457,364 of the decimal expansion (the 457,364ordinal-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.
