Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483644, here are decompositions:

47 + 31483597 = 31483644
61 + 31483583 = 31483644
67 + 31483577 = 31483644
97 + 31483547 = 31483644
151 + 31483493 = 31483644
173 + 31483471 = 31483644
191 + 31483453 = 31483644
197 + 31483447 = 31483644

Showing the first eight; more decompositions exist.
