Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294979420, here are decompositions:

  • 3 + 4294979417 = 4294979420
  • 13 + 4294979407 = 4294979420
  • 37 + 4294979383 = 4294979420
  • 367 + 4294979053 = 4294979420
  • 373 + 4294979047 = 4294979420
  • 397 + 4294979023 = 4294979420
  • 547 + 4294978873 = 4294979420
  • 643 + 4294978777 = 4294979420

Showing the first eight; more decompositions exist.
