Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609850, here are decompositions:

3 + 31609847 = 31609850
31 + 31609819 = 31609850
37 + 31609813 = 31609850
73 + 31609777 = 31609850
109 + 31609741 = 31609850
127 + 31609723 = 31609850
157 + 31609693 = 31609850
241 + 31609609 = 31609850

Showing the first eight; more decompositions exist.
