Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130888, here are decompositions:

  • 29 + 130859 = 130888
  • 47 + 130841 = 130888
  • 59 + 130829 = 130888
  • 71 + 130817 = 130888
  • 101 + 130787 = 130888
  • 239 + 130649 = 130888
  • 257 + 130631 = 130888
  • 269 + 130619 = 130888

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 130,888 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 130888 first appears in π at position 621,053 of the decimal expansion (the 621,053ordinal-suffix:rd 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.
