Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584274, here are decompositions:

  • 151 + 2147584123 = 2147584274
  • 211 + 2147584063 = 2147584274
  • 307 + 2147583967 = 2147584274
  • 313 + 2147583961 = 2147584274
  • 331 + 2147583943 = 2147584274
  • 337 + 2147583937 = 2147584274
  • 571 + 2147583703 = 2147584274
  • 643 + 2147583631 = 2147584274

Showing the first eight; more decompositions exist.
