Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645088, here are decompositions:

7 + 8645081 = 8645088
17 + 8645071 = 8645088
41 + 8645047 = 8645088
59 + 8645029 = 8645088
79 + 8645009 = 8645088
97 + 8644991 = 8645088
131 + 8644957 = 8645088
139 + 8644949 = 8645088

Showing the first eight; more decompositions exist.
