Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30586, here are decompositions:

  • 29 + 30557 = 30586
  • 47 + 30539 = 30586
  • 89 + 30497 = 30586
  • 137 + 30449 = 30586
  • 197 + 30389 = 30586
  • 239 + 30347 = 30586
  • 263 + 30323 = 30586
  • 293 + 30293 = 30586

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 30586 first appears in π at position 25,594 of the decimal expansion (the 25,594ordinal-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.
