Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724618, here are decompositions:

  • 17 + 8724601 = 8724618
  • 29 + 8724589 = 8724618
  • 59 + 8724559 = 8724618
  • 107 + 8724511 = 8724618
  • 131 + 8724487 = 8724618
  • 139 + 8724479 = 8724618
  • 151 + 8724467 = 8724618
  • 157 + 8724461 = 8724618

Showing the first eight; more decompositions exist.
