Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534070, here are decompositions:

3 + 31534067 = 31534070
13 + 31534057 = 31534070
19 + 31534051 = 31534070
37 + 31534033 = 31534070
103 + 31533967 = 31534070
151 + 31533919 = 31534070
199 + 31533871 = 31534070
223 + 31533847 = 31534070

Showing the first eight; more decompositions exist.
