Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294999900, here are decompositions:

  • 11 + 4294999889 = 4294999900
  • 83 + 4294999817 = 4294999900
  • 131 + 4294999769 = 4294999900
  • 137 + 4294999763 = 4294999900
  • 167 + 4294999733 = 4294999900
  • 173 + 4294999727 = 4294999900
  • 179 + 4294999721 = 4294999900
  • 353 + 4294999547 = 4294999900

Showing the first eight; more decompositions exist.
