Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600342, here are decompositions:

23 + 31600319 = 31600342
41 + 31600301 = 31600342
83 + 31600259 = 31600342
149 + 31600193 = 31600342
239 + 31600103 = 31600342
281 + 31600061 = 31600342
383 + 31599959 = 31600342
401 + 31599941 = 31600342

Showing the first eight; more decompositions exist.
