Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294991900, here are decompositions:

  • 7 + 4294991893 = 4294991900
  • 13 + 4294991887 = 4294991900
  • 61 + 4294991839 = 4294991900
  • 79 + 4294991821 = 4294991900
  • 151 + 4294991749 = 4294991900
  • 163 + 4294991737 = 4294991900
  • 223 + 4294991677 = 4294991900
  • 313 + 4294991587 = 4294991900

Showing the first eight; more decompositions exist.
