Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55890, here are decompositions:

  • 19 + 55871 = 55890
  • 41 + 55849 = 55890
  • 47 + 55843 = 55890
  • 53 + 55837 = 55890
  • 61 + 55829 = 55890
  • 67 + 55823 = 55890
  • 71 + 55819 = 55890
  • 73 + 55817 = 55890

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 55890 first appears in π at position 9,033 of the decimal expansion (the 9,033ordinal-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.
