Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489228, here are decompositions:

  • 139 + 2147489089 = 2147489228
  • 151 + 2147489077 = 2147489228
  • 211 + 2147489017 = 2147489228
  • 487 + 2147488741 = 2147489228
  • 811 + 2147488417 = 2147489228
  • 1117 + 2147488111 = 2147489228
  • 1201 + 2147488027 = 2147489228
  • 1297 + 2147487931 = 2147489228

Showing the first eight; more decompositions exist.
