Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511948, here are decompositions:

  • 89 + 511859 = 511948
  • 137 + 511811 = 511948
  • 191 + 511757 = 511948
  • 257 + 511691 = 511948
  • 317 + 511631 = 511948
  • 389 + 511559 = 511948
  • 461 + 511487 = 511948
  • 491 + 511457 = 511948

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 511,948 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 511948 first appears in π at position 193,611 of the decimal expansion (the 193,611ordinal-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.
