Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5500, here are decompositions:

  • 17 + 5483 = 5500
  • 23 + 5477 = 5500
  • 29 + 5471 = 5500
  • 59 + 5441 = 5500
  • 83 + 5417 = 5500
  • 101 + 5399 = 5500
  • 107 + 5393 = 5500
  • 113 + 5387 = 5500

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 5500 first appears in π at position 6,444 of the decimal expansion (the 6,444ordinal-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.
