Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991000, here are decompositions:

  • 229 + 4294990771 = 4294991000
  • 271 + 4294990729 = 4294991000
  • 277 + 4294990723 = 4294991000
  • 379 + 4294990621 = 4294991000
  • 439 + 4294990561 = 4294991000
  • 523 + 4294990477 = 4294991000
  • 571 + 4294990429 = 4294991000
  • 577 + 4294990423 = 4294991000

Showing the first eight; more decompositions exist.
