Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600992, here are decompositions:

23 + 31600969 = 31600992
109 + 31600883 = 31600992
131 + 31600861 = 31600992
149 + 31600843 = 31600992
191 + 31600801 = 31600992
193 + 31600799 = 31600992
239 + 31600753 = 31600992
251 + 31600741 = 31600992

Showing the first eight; more decompositions exist.
