Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486182, here are decompositions:

19 + 31486163 = 31486182
53 + 31486129 = 31486182
59 + 31486123 = 31486182
61 + 31486121 = 31486182
73 + 31486109 = 31486182
149 + 31486033 = 31486182
173 + 31486009 = 31486182
223 + 31485959 = 31486182

Showing the first eight; more decompositions exist.
