Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 36520, here are decompositions:

  • 23 + 36497 = 36520
  • 41 + 36479 = 36520
  • 47 + 36473 = 36520
  • 53 + 36467 = 36520
  • 131 + 36389 = 36520
  • 137 + 36383 = 36520
  • 167 + 36353 = 36520
  • 179 + 36341 = 36520

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 36520 first appears in π at position 12,318 of the decimal expansion (the 12,318ordinal-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.
