Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469802, here are decompositions:

  • 173 + 2147469629 = 2147469802
  • 281 + 2147469521 = 2147469802
  • 311 + 2147469491 = 2147469802
  • 353 + 2147469449 = 2147469802
  • 383 + 2147469419 = 2147469802
  • 563 + 2147469239 = 2147469802
  • 701 + 2147469101 = 2147469802
  • 761 + 2147469041 = 2147469802

Showing the first eight; more decompositions exist.
