Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31662, here are decompositions:

5 + 31657 = 31662
13 + 31649 = 31662
19 + 31643 = 31662
61 + 31601 = 31662
79 + 31583 = 31662
89 + 31573 = 31662
131 + 31531 = 31662
149 + 31513 = 31662

Showing the first eight; more decompositions exist.
