Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186548, here are decompositions:

  • 67 + 186481 = 186548
  • 79 + 186469 = 186548
  • 97 + 186451 = 186548
  • 151 + 186397 = 186548
  • 157 + 186391 = 186548
  • 277 + 186271 = 186548
  • 337 + 186211 = 186548
  • 499 + 186049 = 186548

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 186,548 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 186548 first appears in π at position 713,289 of the decimal expansion (the 713,289ordinal-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.
