Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645470, here are decompositions:

  • 89 + 8645381 = 8645470
  • 227 + 8645243 = 8645470
  • 233 + 8645237 = 8645470
  • 347 + 8645123 = 8645470
  • 389 + 8645081 = 8645470
  • 461 + 8645009 = 8645470
  • 479 + 8644991 = 8645470
  • 521 + 8644949 = 8645470

Showing the first eight; more decompositions exist.
