Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513014, here are decompositions:

7 + 31513007 = 31513014
11 + 31513003 = 31513014
17 + 31512997 = 31513014
23 + 31512991 = 31513014
67 + 31512947 = 31513014
101 + 31512913 = 31513014
107 + 31512907 = 31513014
173 + 31512841 = 31513014

Showing the first eight; more decompositions exist.
