Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655636, here are decompositions:

5 + 8655631 = 8655636
7 + 8655629 = 8655636
13 + 8655623 = 8655636
109 + 8655527 = 8655636
139 + 8655497 = 8655636
179 + 8655457 = 8655636
233 + 8655403 = 8655636
293 + 8655343 = 8655636

Showing the first eight; more decompositions exist.
