Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600282, here are decompositions:

3 + 31600279 = 31600282
5 + 31600277 = 31600282
23 + 31600259 = 31600282
89 + 31600193 = 31600282
149 + 31600133 = 31600282
179 + 31600103 = 31600282
239 + 31600043 = 31600282
281 + 31600001 = 31600282

Showing the first eight; more decompositions exist.
