Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655398, here are decompositions:

67 + 8655331 = 8655398
139 + 8655259 = 8655398
181 + 8655217 = 8655398
439 + 8654959 = 8655398
457 + 8654941 = 8655398
709 + 8654689 = 8655398
757 + 8654641 = 8655398
877 + 8654521 = 8655398

Showing the first eight; more decompositions exist.
