Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559066, here are decompositions:

73 + 31558993 = 31559066
103 + 31558963 = 31559066
109 + 31558957 = 31559066
127 + 31558939 = 31559066
139 + 31558927 = 31559066
223 + 31558843 = 31559066
277 + 31558789 = 31559066
307 + 31558759 = 31559066

Showing the first eight; more decompositions exist.
