Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516954, here are decompositions:

3 + 31516951 = 31516954
113 + 31516841 = 31516954
167 + 31516787 = 31516954
173 + 31516781 = 31516954
197 + 31516757 = 31516954
251 + 31516703 = 31516954
257 + 31516697 = 31516954
383 + 31516571 = 31516954

Showing the first eight; more decompositions exist.
