Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626002, here are decompositions:

181 + 31625821 = 31626002
223 + 31625779 = 31626002
229 + 31625773 = 31626002
241 + 31625761 = 31626002
271 + 31625731 = 31626002
349 + 31625653 = 31626002
439 + 31625563 = 31626002
571 + 31625431 = 31626002

Showing the first eight; more decompositions exist.
