Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491254, here are decompositions:

  • 5 + 2147491249 = 2147491254
  • 17 + 2147491237 = 2147491254
  • 31 + 2147491223 = 2147491254
  • 37 + 2147491217 = 2147491254
  • 53 + 2147491201 = 2147491254
  • 61 + 2147491193 = 2147491254
  • 127 + 2147491127 = 2147491254
  • 131 + 2147491123 = 2147491254

Showing the first eight; more decompositions exist.
