Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147558636, here are decompositions:

  • 7 + 2147558629 = 2147558636
  • 43 + 2147558593 = 2147558636
  • 109 + 2147558527 = 2147558636
  • 277 + 2147558359 = 2147558636
  • 409 + 2147558227 = 2147558636
  • 463 + 2147558173 = 2147558636
  • 577 + 2147558059 = 2147558636
  • 709 + 2147557927 = 2147558636

Showing the first eight; more decompositions exist.
