Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978778, here are decompositions:

  • 151 + 4294978627 = 4294978778
  • 379 + 4294978399 = 4294978778
  • 397 + 4294978381 = 4294978778
  • 547 + 4294978231 = 4294978778
  • 577 + 4294978201 = 4294978778
  • 631 + 4294978147 = 4294978778
  • 691 + 4294978087 = 4294978778
  • 751 + 4294978027 = 4294978778

Showing the first eight; more decompositions exist.
