Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611648, here are decompositions:

7 + 31611641 = 31611648
31 + 31611617 = 31611648
41 + 31611607 = 31611648
67 + 31611581 = 31611648
71 + 31611577 = 31611648
109 + 31611539 = 31611648
139 + 31611509 = 31611648
181 + 31611467 = 31611648

Showing the first eight; more decompositions exist.
