Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517464, here are decompositions:

23 + 31517441 = 31517464
47 + 31517417 = 31517464
53 + 31517411 = 31517464
71 + 31517393 = 31517464
191 + 31517273 = 31517464
197 + 31517267 = 31517464
233 + 31517231 = 31517464
257 + 31517207 = 31517464

Showing the first eight; more decompositions exist.
