Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517244, here are decompositions:

13 + 31517231 = 31517244
37 + 31517207 = 31517244
47 + 31517197 = 31517244
181 + 31517063 = 31517244
223 + 31517021 = 31517244
233 + 31517011 = 31517244
251 + 31516993 = 31517244
263 + 31516981 = 31517244

Showing the first eight; more decompositions exist.
