Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559046, here are decompositions:

19 + 31559027 = 31559046
53 + 31558993 = 31559046
73 + 31558973 = 31559046
83 + 31558963 = 31559046
89 + 31558957 = 31559046
107 + 31558939 = 31559046
149 + 31558897 = 31559046
163 + 31558883 = 31559046

Showing the first eight; more decompositions exist.
