Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4295071820, here are decompositions:

  • 31 + 4295071789 = 4295071820
  • 79 + 4295071741 = 4295071820
  • 211 + 4295071609 = 4295071820
  • 229 + 4295071591 = 4295071820
  • 307 + 4295071513 = 4295071820
  • 379 + 4295071441 = 4295071820
  • 397 + 4295071423 = 4295071820
  • 409 + 4295071411 = 4295071820

Showing the first eight; more decompositions exist.
