Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626134, here are decompositions:

3 + 31626131 = 31626134
61 + 31626073 = 31626134
181 + 31625953 = 31626134
223 + 31625911 = 31626134
313 + 31625821 = 31626134
367 + 31625767 = 31626134
373 + 31625761 = 31626134
487 + 31625647 = 31626134

Showing the first eight; more decompositions exist.
