Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655148, here are decompositions:

101 + 8655047 = 8655148
107 + 8655041 = 8655148
137 + 8655011 = 8655148
167 + 8654981 = 8655148
251 + 8654897 = 8655148
311 + 8654837 = 8655148
389 + 8654759 = 8655148
419 + 8654729 = 8655148

Showing the first eight; more decompositions exist.
