Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517424, here are decompositions:

7 + 31517417 = 31517424
11 + 31517413 = 31517424
13 + 31517411 = 31517424
17 + 31517407 = 31517424
31 + 31517393 = 31517424
151 + 31517273 = 31517424
157 + 31517267 = 31517424
181 + 31517243 = 31517424

Showing the first eight; more decompositions exist.
