Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517376, here are decompositions:

103 + 31517273 = 31517376
109 + 31517267 = 31517376
179 + 31517197 = 31517376
227 + 31517149 = 31517376
313 + 31517063 = 31517376
337 + 31517039 = 31517376
349 + 31517027 = 31517376
383 + 31516993 = 31517376

Showing the first eight; more decompositions exist.
