Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645202, here are decompositions:

23 + 8645179 = 8645202
61 + 8645141 = 8645202
79 + 8645123 = 8645202
89 + 8645113 = 8645202
131 + 8645071 = 8645202
149 + 8645053 = 8645202
173 + 8645029 = 8645202
179 + 8645023 = 8645202

Showing the first eight; more decompositions exist.
