Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600452, here are decompositions:

5 + 31600447 = 31600452
11 + 31600441 = 31600452
29 + 31600423 = 31600452
31 + 31600421 = 31600452
43 + 31600409 = 31600452
151 + 31600301 = 31600452
173 + 31600279 = 31600452
179 + 31600273 = 31600452

Showing the first eight; more decompositions exist.
