Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469658, here are decompositions:

  • 29 + 2147469629 = 2147469658
  • 137 + 2147469521 = 2147469658
  • 167 + 2147469491 = 2147469658
  • 239 + 2147469419 = 2147469658
  • 311 + 2147469347 = 2147469658
  • 419 + 2147469239 = 2147469658
  • 479 + 2147469179 = 2147469658
  • 557 + 2147469101 = 2147469658

Showing the first eight; more decompositions exist.
