Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65286, here are decompositions:

  • 17 + 65269 = 65286
  • 19 + 65267 = 65286
  • 29 + 65257 = 65286
  • 47 + 65239 = 65286
  • 73 + 65213 = 65286
  • 83 + 65203 = 65286
  • 103 + 65183 = 65286
  • 107 + 65179 = 65286

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65286 first appears in π at position 5,407 of the decimal expansion (the 5,407ordinal-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.
