Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620570, here are decompositions:

  • 3 + 8620567 = 8620570
  • 17 + 8620553 = 8620570
  • 41 + 8620529 = 8620570
  • 71 + 8620499 = 8620570
  • 263 + 8620307 = 8620570
  • 281 + 8620289 = 8620570
  • 293 + 8620277 = 8620570
  • 311 + 8620259 = 8620570

Showing the first eight; more decompositions exist.
