Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469490, here are decompositions:

  • 41 + 2147469449 = 2147469490
  • 71 + 2147469419 = 2147469490
  • 227 + 2147469263 = 2147469490
  • 251 + 2147469239 = 2147469490
  • 311 + 2147469179 = 2147469490
  • 317 + 2147469173 = 2147469490
  • 359 + 2147469131 = 2147469490
  • 389 + 2147469101 = 2147469490

Showing the first eight; more decompositions exist.
