Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991880, here are decompositions:

  • 7 + 4294991873 = 4294991880
  • 19 + 4294991861 = 4294991880
  • 31 + 4294991849 = 4294991880
  • 41 + 4294991839 = 4294991880
  • 43 + 4294991837 = 4294991880
  • 59 + 4294991821 = 4294991880
  • 131 + 4294991749 = 4294991880
  • 167 + 4294991713 = 4294991880

Showing the first eight; more decompositions exist.
