Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626362, here are decompositions:

3 + 31626359 = 31626362
283 + 31626079 = 31626362
409 + 31625953 = 31626362
541 + 31625821 = 31626362
601 + 31625761 = 31626362
631 + 31625731 = 31626362
709 + 31625653 = 31626362
853 + 31625509 = 31626362

Showing the first eight; more decompositions exist.
