Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469886, here are decompositions:

  • 5 + 2147469881 = 2147469886
  • 227 + 2147469659 = 2147469886
  • 257 + 2147469629 = 2147469886
  • 293 + 2147469593 = 2147469886
  • 467 + 2147469419 = 2147469886
  • 557 + 2147469329 = 2147469886
  • 647 + 2147469239 = 2147469886
  • 773 + 2147469113 = 2147469886

Showing the first eight; more decompositions exist.
