Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600332, here are decompositions:

13 + 31600319 = 31600332
31 + 31600301 = 31600332
41 + 31600291 = 31600332
53 + 31600279 = 31600332
59 + 31600273 = 31600332
73 + 31600259 = 31600332
131 + 31600201 = 31600332
139 + 31600193 = 31600332

Showing the first eight; more decompositions exist.
