Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294992978, here are decompositions:

  • 5 + 4294992973 = 4294992978
  • 7 + 4294992971 = 4294992978
  • 37 + 4294992941 = 4294992978
  • 79 + 4294992899 = 4294992978
  • 137 + 4294992841 = 4294992978
  • 181 + 4294992797 = 4294992978
  • 229 + 4294992749 = 4294992978
  • 317 + 4294992661 = 4294992978

Showing the first eight; more decompositions exist.
