Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685942, here are decompositions:

  • 19 + 8685923 = 8685942
  • 29 + 8685913 = 8685942
  • 79 + 8685863 = 8685942
  • 151 + 8685791 = 8685942
  • 173 + 8685769 = 8685942
  • 179 + 8685763 = 8685942
  • 191 + 8685751 = 8685942
  • 193 + 8685749 = 8685942

Showing the first eight; more decompositions exist.
