Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51300, here are decompositions:

  • 13 + 51287 = 51300
  • 17 + 51283 = 51300
  • 37 + 51263 = 51300
  • 43 + 51257 = 51300
  • 59 + 51241 = 51300
  • 61 + 51239 = 51300
  • 71 + 51229 = 51300
  • 83 + 51217 = 51300

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51300 first appears in π at position 6,233 of the decimal expansion (the 6,233ordinal-suffix:rd 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.
