Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469730, here are decompositions:

  • 71 + 2147469659 = 2147469730
  • 101 + 2147469629 = 2147469730
  • 137 + 2147469593 = 2147469730
  • 239 + 2147469491 = 2147469730
  • 281 + 2147469449 = 2147469730
  • 311 + 2147469419 = 2147469730
  • 383 + 2147469347 = 2147469730
  • 401 + 2147469329 = 2147469730

Showing the first eight; more decompositions exist.
