Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486012, here are decompositions:

3 + 31486009 = 31486012
53 + 31485959 = 31486012
59 + 31485953 = 31486012
71 + 31485941 = 31486012
179 + 31485833 = 31486012
263 + 31485749 = 31486012
269 + 31485743 = 31486012
359 + 31485653 = 31486012

Showing the first eight; more decompositions exist.
