Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531634, here are decompositions:

7 + 31531627 = 31531634
151 + 31531483 = 31531634
163 + 31531471 = 31531634
181 + 31531453 = 31531634
331 + 31531303 = 31531634
367 + 31531267 = 31531634
373 + 31531261 = 31531634
571 + 31531063 = 31531634

Showing the first eight; more decompositions exist.
