Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645106, here are decompositions:

53 + 8645053 = 8645106
59 + 8645047 = 8645106
83 + 8645023 = 8645106
97 + 8645009 = 8645106
149 + 8644957 = 8645106
157 + 8644949 = 8645106
179 + 8644927 = 8645106
193 + 8644913 = 8645106

Showing the first eight; more decompositions exist.
