Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486278, here are decompositions:

  • 29 + 2147486249 = 2147486278
  • 131 + 2147486147 = 2147486278
  • 149 + 2147486129 = 2147486278
  • 167 + 2147486111 = 2147486278
  • 257 + 2147486021 = 2147486278
  • 269 + 2147486009 = 2147486278
  • 389 + 2147485889 = 2147486278
  • 401 + 2147485877 = 2147486278

Showing the first eight; more decompositions exist.
