Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520362, here are decompositions:

23 + 31520339 = 31520362
53 + 31520309 = 31520362
191 + 31520171 = 31520362
353 + 31520009 = 31520362
443 + 31519919 = 31520362
569 + 31519793 = 31520362
593 + 31519769 = 31520362
659 + 31519703 = 31520362

Showing the first eight; more decompositions exist.
