Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513284, here are decompositions:

  • 7 + 513277 = 513284
  • 127 + 513157 = 513284
  • 181 + 513103 = 513284
  • 271 + 513013 = 513284
  • 283 + 513001 = 513284
  • 307 + 512977 = 513284
  • 367 + 512917 = 513284
  • 463 + 512821 = 513284

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 513,284 and was likely granted around 1893.

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

Position in π

The digit sequence 513284 first appears in π at position 746,189 of the decimal expansion (the 746,189ordinal-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.
