Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625846, here are decompositions:

3 + 31625843 = 31625846
67 + 31625779 = 31625846
73 + 31625773 = 31625846
79 + 31625767 = 31625846
193 + 31625653 = 31625846
199 + 31625647 = 31625846
229 + 31625617 = 31625846
283 + 31625563 = 31625846

Showing the first eight; more decompositions exist.
