Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655608, here are decompositions:

151 + 8655457 = 8655608
277 + 8655331 = 8655608
349 + 8655259 = 8655608
397 + 8655211 = 8655608
571 + 8655037 = 8655608
601 + 8655007 = 8655608
691 + 8654917 = 8655608
769 + 8654839 = 8655608

Showing the first eight; more decompositions exist.
