Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518248, here are decompositions:

  • 11 + 518237 = 518248
  • 41 + 518207 = 518248
  • 89 + 518159 = 518248
  • 149 + 518099 = 518248
  • 191 + 518057 = 518248
  • 257 + 517991 = 518248
  • 281 + 517967 = 518248
  • 317 + 517931 = 518248

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 518,248 and was likely granted around 1894.

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

Position in π

The digit sequence 518248 first appears in π at position 373,297 of the decimal expansion (the 373,297ordinal-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.
