Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655646, here are decompositions:

5 + 8655641 = 8655646
17 + 8655629 = 8655646
23 + 8655623 = 8655646
149 + 8655497 = 8655646
359 + 8655287 = 8655646
383 + 8655263 = 8655646
449 + 8655197 = 8655646
479 + 8655167 = 8655646

Showing the first eight; more decompositions exist.
