Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685990, here are decompositions:

  • 11 + 8685979 = 8685990
  • 23 + 8685967 = 8685990
  • 29 + 8685961 = 8685990
  • 37 + 8685953 = 8685990
  • 41 + 8685949 = 8685990
  • 67 + 8685923 = 8685990
  • 73 + 8685917 = 8685990
  • 97 + 8685893 = 8685990

Showing the first eight; more decompositions exist.
