Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65390, here are decompositions:

  • 19 + 65371 = 65390
  • 37 + 65353 = 65390
  • 67 + 65323 = 65390
  • 97 + 65293 = 65390
  • 103 + 65287 = 65390
  • 151 + 65239 = 65390
  • 211 + 65179 = 65390
  • 223 + 65167 = 65390

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65390 first appears in π at position 20,006 of the decimal expansion (the 20,006ordinal-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.
