Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489556, here are decompositions:

  • 13 + 2147489543 = 2147489556
  • 19 + 2147489537 = 2147489556
  • 53 + 2147489503 = 2147489556
  • 73 + 2147489483 = 2147489556
  • 83 + 2147489473 = 2147489556
  • 257 + 2147489299 = 2147489556
  • 293 + 2147489263 = 2147489556
  • 313 + 2147489243 = 2147489556

Showing the first eight; more decompositions exist.
