Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65404, here are decompositions:

  • 11 + 65393 = 65404
  • 23 + 65381 = 65404
  • 47 + 65357 = 65404
  • 137 + 65267 = 65404
  • 191 + 65213 = 65404
  • 233 + 65171 = 65404
  • 257 + 65147 = 65404
  • 263 + 65141 = 65404

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65404 first appears in π at position 271,684 of the decimal expansion (the 271,684ordinal-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.
