Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55730, here are decompositions:

  • 13 + 55717 = 55730
  • 19 + 55711 = 55730
  • 67 + 55663 = 55730
  • 97 + 55633 = 55730
  • 109 + 55621 = 55730
  • 127 + 55603 = 55730
  • 151 + 55579 = 55730
  • 229 + 55501 = 55730

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 55730 first appears in π at position 4,003 of the decimal expansion (the 4,003ordinal-suffix:rd 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.
