Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517324, here are decompositions:

127 + 31517197 = 31517324
313 + 31517011 = 31517324
331 + 31516993 = 31517324
373 + 31516951 = 31517324
547 + 31516777 = 31517324
571 + 31516753 = 31517324
691 + 31516633 = 31517324
757 + 31516567 = 31517324

Showing the first eight; more decompositions exist.
