Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5566, here are decompositions:

  • 3 + 5563 = 5566
  • 47 + 5519 = 5566
  • 59 + 5507 = 5566
  • 83 + 5483 = 5566
  • 89 + 5477 = 5566
  • 149 + 5417 = 5566
  • 167 + 5399 = 5566
  • 173 + 5393 = 5566

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 5566 first appears in π at position 10,146 of the decimal expansion (the 10,146ordinal-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.
