Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294956638, here are decompositions:

  • 97 + 4294956541 = 4294956638
  • 109 + 4294956529 = 4294956638
  • 421 + 4294956217 = 4294956638
  • 487 + 4294956151 = 4294956638
  • 727 + 4294955911 = 4294956638
  • 751 + 4294955887 = 4294956638
  • 769 + 4294955869 = 4294956638
  • 1471 + 4294955167 = 4294956638

Showing the first eight; more decompositions exist.
