Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600162, here are decompositions:

5 + 31600157 = 31600162
29 + 31600133 = 31600162
59 + 31600103 = 31600162
101 + 31600061 = 31600162
233 + 31599929 = 31600162
353 + 31599809 = 31600162
389 + 31599773 = 31600162
401 + 31599761 = 31600162

Showing the first eight; more decompositions exist.
