Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501914, here are decompositions:

7 + 31501907 = 31501914
53 + 31501861 = 31501914
83 + 31501831 = 31501914
107 + 31501807 = 31501914
163 + 31501751 = 31501914
173 + 31501741 = 31501914
193 + 31501721 = 31501914
281 + 31501633 = 31501914

Showing the first eight; more decompositions exist.
