Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483584, here are decompositions:

7 + 31483577 = 31483584
31 + 31483553 = 31483584
37 + 31483547 = 31483584
113 + 31483471 = 31483584
127 + 31483457 = 31483584
131 + 31483453 = 31483584
137 + 31483447 = 31483584
151 + 31483433 = 31483584

Showing the first eight; more decompositions exist.
