Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501410, here are decompositions:

7 + 31501403 = 31501410
11 + 31501399 = 31501410
23 + 31501387 = 31501410
79 + 31501331 = 31501410
89 + 31501321 = 31501410
97 + 31501313 = 31501410
107 + 31501303 = 31501410
163 + 31501247 = 31501410

Showing the first eight; more decompositions exist.
