Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147583980, here are decompositions:

  • 13 + 2147583967 = 2147583980
  • 19 + 2147583961 = 2147583980
  • 37 + 2147583943 = 2147583980
  • 43 + 2147583937 = 2147583980
  • 151 + 2147583829 = 2147583980
  • 181 + 2147583799 = 2147583980
  • 271 + 2147583709 = 2147583980
  • 277 + 2147583703 = 2147583980

Showing the first eight; more decompositions exist.
