Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678438, here are decompositions:

  • 79 + 8678359 = 8678438
  • 127 + 8678311 = 8678438
  • 277 + 8678161 = 8678438
  • 409 + 8678029 = 8678438
  • 487 + 8677951 = 8678438
  • 547 + 8677891 = 8678438
  • 757 + 8677681 = 8678438
  • 787 + 8677651 = 8678438

Showing the first eight; more decompositions exist.
