Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294992780, here are decompositions:

  • 31 + 4294992749 = 4294992780
  • 97 + 4294992683 = 4294992780
  • 103 + 4294992677 = 4294992780
  • 137 + 4294992643 = 4294992780
  • 233 + 4294992547 = 4294992780
  • 263 + 4294992517 = 4294992780
  • 307 + 4294992473 = 4294992780
  • 313 + 4294992467 = 4294992780

Showing the first eight; more decompositions exist.
