Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978886, here are decompositions:

  • 13 + 4294978873 = 4294978886
  • 19 + 4294978867 = 4294978886
  • 109 + 4294978777 = 4294978886
  • 157 + 4294978729 = 4294978886
  • 397 + 4294978489 = 4294978886
  • 487 + 4294978399 = 4294978886
  • 577 + 4294978309 = 4294978886
  • 739 + 4294978147 = 4294978886

Showing the first eight; more decompositions exist.
