Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972872, here are decompositions:

  • 5 + 4294972867 = 4294972872
  • 11 + 4294972861 = 4294972872
  • 13 + 4294972859 = 4294972872
  • 79 + 4294972793 = 4294972872
  • 83 + 4294972789 = 4294972872
  • 263 + 4294972609 = 4294972872
  • 269 + 4294972603 = 4294972872
  • 293 + 4294972579 = 4294972872

Showing the first eight; more decompositions exist.
