Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559030, here are decompositions:

3 + 31559027 = 31559030
37 + 31558993 = 31559030
67 + 31558963 = 31559030
73 + 31558957 = 31559030
103 + 31558927 = 31559030
199 + 31558831 = 31559030
211 + 31558819 = 31559030
241 + 31558789 = 31559030

Showing the first eight; more decompositions exist.
