Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10000, here are decompositions:

  • 59 + 9941 = 10000
  • 71 + 9929 = 10000
  • 113 + 9887 = 10000
  • 149 + 9851 = 10000
  • 167 + 9833 = 10000
  • 197 + 9803 = 10000
  • 233 + 9767 = 10000
  • 251 + 9749 = 10000

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10000 first appears in π at position 387,791 of the decimal expansion (the 387,791ordinal-suffix:st 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.
