Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483600, here are decompositions:

3 + 31483597 = 31483600
17 + 31483583 = 31483600
23 + 31483577 = 31483600
47 + 31483553 = 31483600
53 + 31483547 = 31483600
107 + 31483493 = 31483600
131 + 31483469 = 31483600
167 + 31483433 = 31483600

Showing the first eight; more decompositions exist.
