Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655284, here are decompositions:

67 + 8655217 = 8655284
73 + 8655211 = 8655284
181 + 8655103 = 8655284
277 + 8655007 = 8655284
367 + 8654917 = 8655284
523 + 8654761 = 8655284
571 + 8654713 = 8655284
643 + 8654641 = 8655284

Showing the first eight; more decompositions exist.
