Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490890, here are decompositions:

  • 7 + 2147490883 = 2147490890
  • 19 + 2147490871 = 2147490890
  • 79 + 2147490811 = 2147490890
  • 151 + 2147490739 = 2147490890
  • 163 + 2147490727 = 2147490890
  • 313 + 2147490577 = 2147490890
  • 439 + 2147490451 = 2147490890
  • 547 + 2147490343 = 2147490890

Showing the first eight; more decompositions exist.
