Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626086, here are decompositions:

7 + 31626079 = 31626086
13 + 31626073 = 31626086
67 + 31626019 = 31626086
307 + 31625779 = 31626086
313 + 31625773 = 31626086
433 + 31625653 = 31626086
439 + 31625647 = 31626086
487 + 31625599 = 31626086

Showing the first eight; more decompositions exist.
