Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559034, here are decompositions:

7 + 31559027 = 31559034
37 + 31558997 = 31559034
41 + 31558993 = 31559034
61 + 31558973 = 31559034
71 + 31558963 = 31559034
107 + 31558927 = 31559034
137 + 31558897 = 31559034
151 + 31558883 = 31559034

Showing the first eight; more decompositions exist.
