Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655186, here are decompositions:

13 + 8655173 = 8655186
19 + 8655167 = 8655186
37 + 8655149 = 8655186
83 + 8655103 = 8655186
139 + 8655047 = 8655186
149 + 8655037 = 8655186
157 + 8655029 = 8655186
179 + 8655007 = 8655186

Showing the first eight; more decompositions exist.
