Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497014, here are decompositions:

7 + 31497007 = 31497014
13 + 31497001 = 31497014
37 + 31496977 = 31497014
67 + 31496947 = 31497014
97 + 31496917 = 31497014
151 + 31496863 = 31497014
223 + 31496791 = 31497014
337 + 31496677 = 31497014

Showing the first eight; more decompositions exist.
