Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618570, here are decompositions:

  • 3 + 8618567 = 8618570
  • 13 + 8618557 = 8618570
  • 127 + 8618443 = 8618570
  • 157 + 8618413 = 8618570
  • 193 + 8618377 = 8618570
  • 241 + 8618329 = 8618570
  • 277 + 8618293 = 8618570
  • 283 + 8618287 = 8618570

Showing the first eight; more decompositions exist.
