Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486134, here are decompositions:

5 + 31486129 = 31486134
11 + 31486123 = 31486134
13 + 31486121 = 31486134
47 + 31486087 = 31486134
101 + 31486033 = 31486134
181 + 31485953 = 31486134
193 + 31485941 = 31486134
241 + 31485893 = 31486134

Showing the first eight; more decompositions exist.
