Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470118, here are decompositions:

  • 7 + 2147470111 = 2147470118
  • 37 + 2147470081 = 2147470118
  • 61 + 2147470057 = 2147470118
  • 337 + 2147469781 = 2147470118
  • 439 + 2147469679 = 2147470118
  • 499 + 2147469619 = 2147470118
  • 1051 + 2147469067 = 2147470118
  • 1117 + 2147469001 = 2147470118

Showing the first eight; more decompositions exist.
