Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645108, here are decompositions:

37 + 8645071 = 8645108
61 + 8645047 = 8645108
79 + 8645029 = 8645108
97 + 8645011 = 8645108
151 + 8644957 = 8645108
181 + 8644927 = 8645108
337 + 8644771 = 8645108
379 + 8644729 = 8645108

Showing the first eight; more decompositions exist.
