Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517056, here are decompositions:

17 + 31517039 = 31517056
29 + 31517027 = 31517056
83 + 31516973 = 31517056
167 + 31516889 = 31517056
269 + 31516787 = 31517056
353 + 31516703 = 31517056
359 + 31516697 = 31517056
443 + 31516613 = 31517056

Showing the first eight; more decompositions exist.
