Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51360, here are decompositions:

  • 11 + 51349 = 51360
  • 13 + 51347 = 51360
  • 17 + 51343 = 51360
  • 19 + 51341 = 51360
  • 31 + 51329 = 51360
  • 53 + 51307 = 51360
  • 73 + 51287 = 51360
  • 97 + 51263 = 51360

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51360 first appears in π at position 177,922 of the decimal expansion (the 177,922ordinal-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.
