Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294954978, here are decompositions:

  • 11 + 4294954967 = 4294954978
  • 239 + 4294954739 = 4294954978
  • 257 + 4294954721 = 4294954978
  • 449 + 4294954529 = 4294954978
  • 557 + 4294954421 = 4294954978
  • 617 + 4294954361 = 4294954978
  • 647 + 4294954331 = 4294954978
  • 701 + 4294954277 = 4294954978

Showing the first eight; more decompositions exist.
