Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600284, here are decompositions:

5 + 31600279 = 31600284
7 + 31600277 = 31600284
11 + 31600273 = 31600284
83 + 31600201 = 31600284
127 + 31600157 = 31600284
151 + 31600133 = 31600284
167 + 31600117 = 31600284
181 + 31600103 = 31600284

Showing the first eight; more decompositions exist.
