Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491556, here are decompositions:

  • 3 + 2147491553 = 2147491556
  • 13 + 2147491543 = 2147491556
  • 19 + 2147491537 = 2147491556
  • 79 + 2147491477 = 2147491556
  • 139 + 2147491417 = 2147491556
  • 283 + 2147491273 = 2147491556
  • 307 + 2147491249 = 2147491556
  • 337 + 2147491219 = 2147491556

Showing the first eight; more decompositions exist.
