Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655818, here are decompositions:

79 + 8655739 = 8655818
97 + 8655721 = 8655818
139 + 8655679 = 8655818
181 + 8655637 = 8655818
397 + 8655421 = 8655818
487 + 8655331 = 8655818
601 + 8655217 = 8655818
607 + 8655211 = 8655818

Showing the first eight; more decompositions exist.
