Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66590, here are decompositions:

  • 3 + 66587 = 66590
  • 19 + 66571 = 66590
  • 37 + 66553 = 66590
  • 61 + 66529 = 66590
  • 67 + 66523 = 66590
  • 127 + 66463 = 66590
  • 229 + 66361 = 66590
  • 421 + 66169 = 66590

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66590 first appears in π at position 42,756 of the decimal expansion (the 42,756ordinal-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.
