Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473248, here are decompositions:

  • 7 + 2147473241 = 2147473248
  • 17 + 2147473231 = 2147473248
  • 31 + 2147473217 = 2147473248
  • 61 + 2147473187 = 2147473248
  • 97 + 2147473151 = 2147473248
  • 127 + 2147473121 = 2147473248
  • 131 + 2147473117 = 2147473248
  • 199 + 2147473049 = 2147473248

Showing the first eight; more decompositions exist.
