Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517416, here are decompositions:

3 + 31517413 = 31517416
5 + 31517411 = 31517416
17 + 31517399 = 31517416
23 + 31517393 = 31517416
149 + 31517267 = 31517416
173 + 31517243 = 31517416
353 + 31517063 = 31517416
389 + 31517027 = 31517416

Showing the first eight; more decompositions exist.
