Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470618, here are decompositions:

  • 89 + 2147470529 = 2147470618
  • 107 + 2147470511 = 2147470618
  • 191 + 2147470427 = 2147470618
  • 257 + 2147470361 = 2147470618
  • 389 + 2147470229 = 2147470618
  • 479 + 2147470139 = 2147470618
  • 599 + 2147470019 = 2147470618
  • 701 + 2147469917 = 2147470618

Showing the first eight; more decompositions exist.
