Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501416, here are decompositions:

7 + 31501409 = 31501416
13 + 31501403 = 31501416
17 + 31501399 = 31501416
29 + 31501387 = 31501416
83 + 31501333 = 31501416
103 + 31501313 = 31501416
113 + 31501303 = 31501416
197 + 31501219 = 31501416

Showing the first eight; more decompositions exist.
