Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188248, here are decompositions:

  • 59 + 188189 = 188248
  • 89 + 188159 = 188248
  • 101 + 188147 = 188248
  • 227 + 188021 = 188248
  • 317 + 187931 = 188248
  • 461 + 187787 = 188248
  • 587 + 187661 = 188248
  • 617 + 187631 = 188248

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 188,248 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 188248 first appears in π at position 711,153 of the decimal expansion (the 711,153ordinal-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.
