Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600492, here are decompositions:

41 + 31600451 = 31600492
71 + 31600421 = 31600492
83 + 31600409 = 31600492
173 + 31600319 = 31600492
191 + 31600301 = 31600492
233 + 31600259 = 31600492
359 + 31600133 = 31600492
389 + 31600103 = 31600492

Showing the first eight; more decompositions exist.
