Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685904, here are decompositions:

  • 11 + 8685893 = 8685904
  • 41 + 8685863 = 8685904
  • 47 + 8685857 = 8685904
  • 113 + 8685791 = 8685904
  • 137 + 8685767 = 8685904
  • 167 + 8685737 = 8685904
  • 173 + 8685731 = 8685904
  • 251 + 8685653 = 8685904

Showing the first eight; more decompositions exist.
