Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501682, here are decompositions:

13 + 31501669 = 31501682
61 + 31501621 = 31501682
151 + 31501531 = 31501682
283 + 31501399 = 31501682
349 + 31501333 = 31501682
379 + 31501303 = 31501682
463 + 31501219 = 31501682
601 + 31501081 = 31501682

Showing the first eight; more decompositions exist.
