Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483686, here are decompositions:

23 + 31483663 = 31483686
37 + 31483649 = 31483686
89 + 31483597 = 31483686
103 + 31483583 = 31483686
109 + 31483577 = 31483686
137 + 31483549 = 31483686
139 + 31483547 = 31483686
193 + 31483493 = 31483686

Showing the first eight; more decompositions exist.
