Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655156, here are decompositions:

7 + 8655149 = 8655156
53 + 8655103 = 8655156
109 + 8655047 = 8655156
127 + 8655029 = 8655156
149 + 8655007 = 8655156
197 + 8654959 = 8655156
239 + 8654917 = 8655156
283 + 8654873 = 8655156

Showing the first eight; more decompositions exist.
