Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655628, here are decompositions:

5 + 8655623 = 8655628
17 + 8655611 = 8655628
101 + 8655527 = 8655628
131 + 8655497 = 8655628
227 + 8655401 = 8655628
257 + 8655371 = 8655628
431 + 8655197 = 8655628
461 + 8655167 = 8655628

Showing the first eight; more decompositions exist.
