Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655650, here are decompositions:

13 + 8655637 = 8655650
19 + 8655631 = 8655650
193 + 8655457 = 8655650
229 + 8655421 = 8655650
307 + 8655343 = 8655650
337 + 8655313 = 8655650
433 + 8655217 = 8655650
439 + 8655211 = 8655650

Showing the first eight; more decompositions exist.
