Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517422, here are decompositions:

5 + 31517417 = 31517422
11 + 31517411 = 31517422
23 + 31517399 = 31517422
29 + 31517393 = 31517422
149 + 31517273 = 31517422
179 + 31517243 = 31517422
191 + 31517231 = 31517422
359 + 31517063 = 31517422

Showing the first eight; more decompositions exist.
