Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739238, here are decompositions:

  • 29 + 8739209 = 8739238
  • 41 + 8739197 = 8739238
  • 71 + 8739167 = 8739238
  • 281 + 8738957 = 8739238
  • 401 + 8738837 = 8739238
  • 479 + 8738759 = 8739238
  • 509 + 8738729 = 8739238
  • 647 + 8738591 = 8739238

Showing the first eight; more decompositions exist.
