Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626344, here are decompositions:

7 + 31626337 = 31626344
97 + 31626247 = 31626344
151 + 31626193 = 31626344
271 + 31626073 = 31626344
433 + 31625911 = 31626344
523 + 31625821 = 31626344
571 + 31625773 = 31626344
577 + 31625767 = 31626344

Showing the first eight; more decompositions exist.
