Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491396, here are decompositions:

  • 47 + 2147491349 = 2147491396
  • 53 + 2147491343 = 2147491396
  • 173 + 2147491223 = 2147491396
  • 179 + 2147491217 = 2147491396
  • 257 + 2147491139 = 2147491396
  • 269 + 2147491127 = 2147491396
  • 353 + 2147491043 = 2147491396
  • 359 + 2147491037 = 2147491396

Showing the first eight; more decompositions exist.
