Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678738, here are decompositions:

  • 31 + 8678707 = 8678738
  • 37 + 8678701 = 8678738
  • 67 + 8678671 = 8678738
  • 139 + 8678599 = 8678738
  • 151 + 8678587 = 8678738
  • 157 + 8678581 = 8678738
  • 181 + 8678557 = 8678738
  • 379 + 8678359 = 8678738

Showing the first eight; more decompositions exist.
