Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511408, here are decompositions:

  • 17 + 511391 = 511408
  • 47 + 511361 = 511408
  • 71 + 511337 = 511408
  • 197 + 511211 = 511408
  • 239 + 511169 = 511408
  • 257 + 511151 = 511408
  • 347 + 511061 = 511408
  • 389 + 511019 = 511408

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 511,408 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 511408 first appears in π at position 108,327 of the decimal expansion (the 108,327ordinal-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.
