Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559006, here are decompositions:

13 + 31558993 = 31559006
43 + 31558963 = 31559006
67 + 31558939 = 31559006
79 + 31558927 = 31559006
109 + 31558897 = 31559006
163 + 31558843 = 31559006
277 + 31558729 = 31559006
313 + 31558693 = 31559006

Showing the first eight; more decompositions exist.
