Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613682, here are decompositions:

13 + 31613669 = 31613682
43 + 31613639 = 31613682
53 + 31613629 = 31613682
59 + 31613623 = 31613682
101 + 31613581 = 31613682
103 + 31613579 = 31613682
131 + 31613551 = 31613682
241 + 31613441 = 31613682

Showing the first eight; more decompositions exist.
