Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486330, here are decompositions:

3 + 31486327 = 31486330
23 + 31486307 = 31486330
41 + 31486289 = 31486330
47 + 31486283 = 31486330
59 + 31486271 = 31486330
101 + 31486229 = 31486330
167 + 31486163 = 31486330
389 + 31485941 = 31486330

Showing the first eight; more decompositions exist.
