Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294999920, here are decompositions:

  • 31 + 4294999889 = 4294999920
  • 103 + 4294999817 = 4294999920
  • 151 + 4294999769 = 4294999920
  • 157 + 4294999763 = 4294999920
  • 179 + 4294999741 = 4294999920
  • 193 + 4294999727 = 4294999920
  • 199 + 4294999721 = 4294999920
  • 373 + 4294999547 = 4294999920

Showing the first eight; more decompositions exist.
