Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486014, here are decompositions:

5 + 31486009 = 31486014
41 + 31485973 = 31486014
61 + 31485953 = 31486014
73 + 31485941 = 31486014
83 + 31485931 = 31486014
97 + 31485917 = 31486014
181 + 31485833 = 31486014
191 + 31485823 = 31486014

Showing the first eight; more decompositions exist.
