Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294989938, here are decompositions:

  • 61 + 4294989877 = 4294989938
  • 139 + 4294989799 = 4294989938
  • 157 + 4294989781 = 4294989938
  • 307 + 4294989631 = 4294989938
  • 607 + 4294989331 = 4294989938
  • 691 + 4294989247 = 4294989938
  • 727 + 4294989211 = 4294989938
  • 769 + 4294989169 = 4294989938

Showing the first eight; more decompositions exist.
