Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294994878, here are decompositions:

  • 29 + 4294994849 = 4294994878
  • 47 + 4294994831 = 4294994878
  • 59 + 4294994819 = 4294994878
  • 71 + 4294994807 = 4294994878
  • 131 + 4294994747 = 4294994878
  • 137 + 4294994741 = 4294994878
  • 227 + 4294994651 = 4294994878
  • 389 + 4294994489 = 4294994878

Showing the first eight; more decompositions exist.
