Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678540, here are decompositions:

  • 67 + 8678473 = 8678540
  • 181 + 8678359 = 8678540
  • 229 + 8678311 = 8678540
  • 337 + 8678203 = 8678540
  • 379 + 8678161 = 8678540
  • 457 + 8678083 = 8678540
  • 487 + 8678053 = 8678540
  • 547 + 8677993 = 8678540

Showing the first eight; more decompositions exist.
