Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497422, here are decompositions:

13 + 31497409 = 31497422
31 + 31497391 = 31497422
109 + 31497313 = 31497422
139 + 31497283 = 31497422
193 + 31497229 = 31497422
199 + 31497223 = 31497422
283 + 31497139 = 31497422
421 + 31497001 = 31497422

Showing the first eight; more decompositions exist.
