Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618662, here are decompositions:

23 + 8618639 = 8618662
71 + 8618591 = 8618662
179 + 8618483 = 8618662
233 + 8618429 = 8618662
389 + 8618273 = 8618662
419 + 8618243 = 8618662
449 + 8618213 = 8618662
599 + 8618063 = 8618662

Showing the first eight; more decompositions exist.
