Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972420, here are decompositions:

  • 83 + 4294972337 = 4294972420
  • 113 + 4294972307 = 4294972420
  • 269 + 4294972151 = 4294972420
  • 311 + 4294972109 = 4294972420
  • 359 + 4294972061 = 4294972420
  • 383 + 4294972037 = 4294972420
  • 491 + 4294971929 = 4294972420
  • 857 + 4294971563 = 4294972420

Showing the first eight; more decompositions exist.
