Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561148, here are decompositions:

  • 47 + 561101 = 561148
  • 89 + 561059 = 561148
  • 101 + 561047 = 561148
  • 179 + 560969 = 561148
  • 251 + 560897 = 561148
  • 257 + 560891 = 561148
  • 311 + 560837 = 561148
  • 479 + 560669 = 561148

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 561,148 and was likely granted around 1895.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 561148 first appears in π at position 242,887 of the decimal expansion (the 242,887ordinal-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.
