Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612208, here are decompositions:

41 + 8612167 = 8612208
89 + 8612119 = 8612208
109 + 8612099 = 8612208
149 + 8612059 = 8612208
151 + 8612057 = 8612208
197 + 8612011 = 8612208
239 + 8611969 = 8612208
317 + 8611891 = 8612208

Showing the first eight; more decompositions exist.
