Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621090, here are decompositions:

  • 3 + 8621087 = 8621090
  • 7 + 8621083 = 8621090
  • 13 + 8621077 = 8621090
  • 43 + 8621047 = 8621090
  • 73 + 8621017 = 8621090
  • 97 + 8620993 = 8621090
  • 139 + 8620951 = 8621090
  • 193 + 8620897 = 8621090

Showing the first eight; more decompositions exist.
