Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490858, here are decompositions:

  • 47 + 2147490811 = 2147490858
  • 59 + 2147490799 = 2147490858
  • 61 + 2147490797 = 2147490858
  • 89 + 2147490769 = 2147490858
  • 127 + 2147490731 = 2147490858
  • 131 + 2147490727 = 2147490858
  • 199 + 2147490659 = 2147490858
  • 269 + 2147490589 = 2147490858

Showing the first eight; more decompositions exist.
