Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10042, here are decompositions:

  • 3 + 10039 = 10042
  • 5 + 10037 = 10042
  • 101 + 9941 = 10042
  • 113 + 9929 = 10042
  • 191 + 9851 = 10042
  • 239 + 9803 = 10042
  • 251 + 9791 = 10042
  • 293 + 9749 = 10042

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10042 first appears in π at position 12,035 of the decimal expansion (the 12,035ordinal-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.
