Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645154, here are decompositions:

13 + 8645141 = 8645154
31 + 8645123 = 8645154
41 + 8645113 = 8645154
73 + 8645081 = 8645154
83 + 8645071 = 8645154
101 + 8645053 = 8645154
107 + 8645047 = 8645154
131 + 8645023 = 8645154

Showing the first eight; more decompositions exist.
