Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517446, here are decompositions:

5 + 31517441 = 31517446
29 + 31517417 = 31517446
47 + 31517399 = 31517446
53 + 31517393 = 31517446
173 + 31517273 = 31517446
179 + 31517267 = 31517446
239 + 31517207 = 31517446
383 + 31517063 = 31517446

Showing the first eight; more decompositions exist.
