Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5558, here are decompositions:

  • 31 + 5527 = 5558
  • 37 + 5521 = 5558
  • 79 + 5479 = 5558
  • 109 + 5449 = 5558
  • 127 + 5431 = 5558
  • 139 + 5419 = 5558
  • 151 + 5407 = 5558
  • 211 + 5347 = 5558

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 5558 first appears in π at position 2,359 of the decimal expansion (the 2,359ordinal-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.
