Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490770, here are decompositions:

  • 31 + 2147490739 = 2147490770
  • 43 + 2147490727 = 2147490770
  • 181 + 2147490589 = 2147490770
  • 193 + 2147490577 = 2147490770
  • 241 + 2147490529 = 2147490770
  • 283 + 2147490487 = 2147490770
  • 307 + 2147490463 = 2147490770
  • 409 + 2147490361 = 2147490770

Showing the first eight; more decompositions exist.
