Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611652, here are decompositions:

5 + 31611647 = 31611652
11 + 31611641 = 31611652
71 + 31611581 = 31611652
113 + 31611539 = 31611652
179 + 31611473 = 31611652
311 + 31611341 = 31611652
353 + 31611299 = 31611652
563 + 31611089 = 31611652

Showing the first eight; more decompositions exist.
