Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517296, here are decompositions:

23 + 31517273 = 31517296
29 + 31517267 = 31517296
53 + 31517243 = 31517296
89 + 31517207 = 31517296
233 + 31517063 = 31517296
257 + 31517039 = 31517296
269 + 31517027 = 31517296
509 + 31516787 = 31517296

Showing the first eight; more decompositions exist.
