Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65528, here are decompositions:

  • 7 + 65521 = 65528
  • 31 + 65497 = 65528
  • 79 + 65449 = 65528
  • 109 + 65419 = 65528
  • 157 + 65371 = 65528
  • 241 + 65287 = 65528
  • 271 + 65257 = 65528
  • 349 + 65179 = 65528

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65528 first appears in π at position 236,396 of the decimal expansion (the 236,396ordinal-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.
