Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483666, here are decompositions:

3 + 31483663 = 31483666
17 + 31483649 = 31483666
83 + 31483583 = 31483666
89 + 31483577 = 31483666
113 + 31483553 = 31483666
173 + 31483493 = 31483666
197 + 31483469 = 31483666
233 + 31483433 = 31483666

Showing the first eight; more decompositions exist.
