Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497416, here are decompositions:

7 + 31497409 = 31497416
79 + 31497337 = 31497416
103 + 31497313 = 31497416
193 + 31497223 = 31497416
229 + 31497187 = 31497416
277 + 31497139 = 31497416
283 + 31497133 = 31497416
409 + 31497007 = 31497416

Showing the first eight; more decompositions exist.
