Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600350, here are decompositions:

17 + 31600333 = 31600350
31 + 31600319 = 31600350
43 + 31600307 = 31600350
59 + 31600291 = 31600350
71 + 31600279 = 31600350
73 + 31600277 = 31600350
149 + 31600201 = 31600350
157 + 31600193 = 31600350

Showing the first eight; more decompositions exist.
