Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470018, here are decompositions:

  • 11 + 2147470007 = 2147470018
  • 101 + 2147469917 = 2147470018
  • 137 + 2147469881 = 2147470018
  • 359 + 2147469659 = 2147470018
  • 389 + 2147469629 = 2147470018
  • 569 + 2147469449 = 2147470018
  • 599 + 2147469419 = 2147470018
  • 839 + 2147469179 = 2147470018

Showing the first eight; more decompositions exist.
