Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42630, here are decompositions:

  • 19 + 42611 = 42630
  • 41 + 42589 = 42630
  • 53 + 42577 = 42630
  • 59 + 42571 = 42630
  • 61 + 42569 = 42630
  • 73 + 42557 = 42630
  • 97 + 42533 = 42630
  • 131 + 42499 = 42630

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 42630 first appears in π at position 33,620 of the decimal expansion (the 33,620ordinal-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.
