Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600338, here are decompositions:

5 + 31600333 = 31600338
19 + 31600319 = 31600338
31 + 31600307 = 31600338
37 + 31600301 = 31600338
47 + 31600291 = 31600338
59 + 31600279 = 31600338
61 + 31600277 = 31600338
79 + 31600259 = 31600338

Showing the first eight; more decompositions exist.
