Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294977840, here are decompositions:

  • 17 + 4294977823 = 4294977840
  • 47 + 4294977793 = 4294977840
  • 53 + 4294977787 = 4294977840
  • 71 + 4294977769 = 4294977840
  • 79 + 4294977761 = 4294977840
  • 89 + 4294977751 = 4294977840
  • 173 + 4294977667 = 4294977840
  • 269 + 4294977571 = 4294977840

Showing the first eight; more decompositions exist.
