Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490780, here are decompositions:

  • 7 + 2147490773 = 2147490780
  • 11 + 2147490769 = 2147490780
  • 41 + 2147490739 = 2147490780
  • 53 + 2147490727 = 2147490780
  • 191 + 2147490589 = 2147490780
  • 199 + 2147490581 = 2147490780
  • 223 + 2147490557 = 2147490780
  • 241 + 2147490539 = 2147490780

Showing the first eight; more decompositions exist.
