Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486218, here are decompositions:

  • 71 + 2147486147 = 2147486218
  • 89 + 2147486129 = 2147486218
  • 107 + 2147486111 = 2147486218
  • 197 + 2147486021 = 2147486218
  • 347 + 2147485871 = 2147486218
  • 359 + 2147485859 = 2147486218
  • 389 + 2147485829 = 2147486218
  • 401 + 2147485817 = 2147486218

Showing the first eight; more decompositions exist.
