Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65538, here are decompositions:

  • 17 + 65521 = 65538
  • 19 + 65519 = 65538
  • 41 + 65497 = 65538
  • 59 + 65479 = 65538
  • 89 + 65449 = 65538
  • 101 + 65437 = 65538
  • 131 + 65407 = 65538
  • 157 + 65381 = 65538

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 65538 first appears in π at position 49,160 of the decimal expansion (the 49,160ordinal-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.
