Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294992980, here are decompositions:

  • 7 + 4294992973 = 4294992980
  • 37 + 4294992943 = 4294992980
  • 67 + 4294992913 = 4294992980
  • 139 + 4294992841 = 4294992980
  • 277 + 4294992703 = 4294992980
  • 337 + 4294992643 = 4294992980
  • 433 + 4294992547 = 4294992980
  • 463 + 4294992517 = 4294992980

Showing the first eight; more decompositions exist.
