Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486788, here are decompositions:

  • 47 + 2147486741 = 2147486788
  • 257 + 2147486531 = 2147486788
  • 281 + 2147486507 = 2147486788
  • 389 + 2147486399 = 2147486788
  • 401 + 2147486387 = 2147486788
  • 449 + 2147486339 = 2147486788
  • 467 + 2147486321 = 2147486788
  • 641 + 2147486147 = 2147486788

Showing the first eight; more decompositions exist.
