Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511478, here are decompositions:

  • 31 + 511447 = 511478
  • 61 + 511417 = 511478
  • 127 + 511351 = 511478
  • 151 + 511327 = 511478
  • 181 + 511297 = 511478
  • 199 + 511279 = 511478
  • 241 + 511237 = 511478
  • 277 + 511201 = 511478

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 511,478 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 511478 first appears in π at position 488,942 of the decimal expansion (the 488,942ordinal-suffix:nd 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.
