Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61536, here are decompositions:

  • 17 + 61519 = 61536
  • 29 + 61507 = 61536
  • 43 + 61493 = 61536
  • 53 + 61483 = 61536
  • 67 + 61469 = 61536
  • 73 + 61463 = 61536
  • 127 + 61409 = 61536
  • 157 + 61379 = 61536

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61536 first appears in π at position 83,375 of the decimal expansion (the 83,375ordinal-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.
