Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517496, here are decompositions:

5 + 31517491 = 31517496
29 + 31517467 = 31517496
79 + 31517417 = 31517496
83 + 31517413 = 31517496
89 + 31517407 = 31517496
97 + 31517399 = 31517496
103 + 31517393 = 31517496
107 + 31517389 = 31517496

Showing the first eight; more decompositions exist.
