Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30580, here are decompositions:

  • 3 + 30577 = 30580
  • 23 + 30557 = 30580
  • 41 + 30539 = 30580
  • 71 + 30509 = 30580
  • 83 + 30497 = 30580
  • 89 + 30491 = 30580
  • 113 + 30467 = 30580
  • 131 + 30449 = 30580

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30580 first appears in π at position 214,959 of the decimal expansion (the 214,959ordinal-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.
