Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655188, here are decompositions:

151 + 8655037 = 8655188
181 + 8655007 = 8655188
229 + 8654959 = 8655188
271 + 8654917 = 8655188
349 + 8654839 = 8655188
379 + 8654809 = 8655188
439 + 8654749 = 8655188
499 + 8654689 = 8655188

Showing the first eight; more decompositions exist.
