Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610592, here are decompositions:

5 + 31610587 = 31610592
11 + 31610581 = 31610592
19 + 31610573 = 31610592
23 + 31610569 = 31610592
29 + 31610563 = 31610592
31 + 31610561 = 31610592
53 + 31610539 = 31610592
71 + 31610521 = 31610592

Showing the first eight; more decompositions exist.
