Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645084, here are decompositions:

3 + 8645081 = 8645084
13 + 8645071 = 8645084
31 + 8645053 = 8645084
37 + 8645047 = 8645084
61 + 8645023 = 8645084
73 + 8645011 = 8645084
127 + 8644957 = 8645084
157 + 8644927 = 8645084

Showing the first eight; more decompositions exist.
