Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655386, here are decompositions:

37 + 8655349 = 8655386
43 + 8655343 = 8655386
73 + 8655313 = 8655386
79 + 8655307 = 8655386
127 + 8655259 = 8655386
283 + 8655103 = 8655386
349 + 8655037 = 8655386
379 + 8655007 = 8655386

Showing the first eight; more decompositions exist.
