Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655626, here are decompositions:

3 + 8655623 = 8655626
193 + 8655433 = 8655626
223 + 8655403 = 8655626
277 + 8655349 = 8655626
283 + 8655343 = 8655626
313 + 8655313 = 8655626
367 + 8655259 = 8655626
409 + 8655217 = 8655626

Showing the first eight; more decompositions exist.
