Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147552228, here are decompositions:

  • 37 + 2147552191 = 2147552228
  • 139 + 2147552089 = 2147552228
  • 229 + 2147551999 = 2147552228
  • 277 + 2147551951 = 2147552228
  • 331 + 2147551897 = 2147552228
  • 379 + 2147551849 = 2147552228
  • 739 + 2147551489 = 2147552228
  • 907 + 2147551321 = 2147552228

Showing the first eight; more decompositions exist.
