Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501414, here are decompositions:

5 + 31501409 = 31501414
11 + 31501403 = 31501414
53 + 31501361 = 31501414
83 + 31501331 = 31501414
101 + 31501313 = 31501414
167 + 31501247 = 31501414
353 + 31501061 = 31501414
467 + 31500947 = 31501414

Showing the first eight; more decompositions exist.
