Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51802, here are decompositions:

  • 5 + 51797 = 51802
  • 53 + 51749 = 51802
  • 83 + 51719 = 51802
  • 89 + 51713 = 51802
  • 239 + 51563 = 51802
  • 251 + 51551 = 51802
  • 263 + 51539 = 51802
  • 281 + 51521 = 51802

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51802 first appears in π at position 75,757 of the decimal expansion (the 75,757ordinal-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.
