Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974872, here are decompositions:

  • 61 + 4294974811 = 4294974872
  • 79 + 4294974793 = 4294974872
  • 103 + 4294974769 = 4294974872
  • 379 + 4294974493 = 4294974872
  • 421 + 4294974451 = 4294974872
  • 541 + 4294974331 = 4294974872
  • 733 + 4294974139 = 4294974872
  • 739 + 4294974133 = 4294974872

Showing the first eight; more decompositions exist.
