Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978940, here are decompositions:

  • 67 + 4294978873 = 4294978940
  • 73 + 4294978867 = 4294978940
  • 163 + 4294978777 = 4294978940
  • 211 + 4294978729 = 4294978940
  • 313 + 4294978627 = 4294978940
  • 349 + 4294978591 = 4294978940
  • 541 + 4294978399 = 4294978940
  • 607 + 4294978333 = 4294978940

Showing the first eight; more decompositions exist.
