Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678090, here are decompositions:

  • 7 + 8678083 = 8678090
  • 37 + 8678053 = 8678090
  • 61 + 8678029 = 8678090
  • 79 + 8678011 = 8678090
  • 97 + 8677993 = 8678090
  • 139 + 8677951 = 8678090
  • 199 + 8677891 = 8678090
  • 331 + 8677759 = 8678090

Showing the first eight; more decompositions exist.
