Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646148, here are decompositions:

29 + 8646119 = 8646148
41 + 8646107 = 8646148
89 + 8646059 = 8646148
131 + 8646017 = 8646148
167 + 8645981 = 8646148
359 + 8645789 = 8646148
389 + 8645759 = 8646148
419 + 8645729 = 8646148

Showing the first eight; more decompositions exist.
