Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655178, here are decompositions:

5 + 8655173 = 8655178
11 + 8655167 = 8655178
29 + 8655149 = 8655178
107 + 8655071 = 8655178
131 + 8655047 = 8655178
137 + 8655041 = 8655178
149 + 8655029 = 8655178
167 + 8655011 = 8655178

Showing the first eight; more decompositions exist.
