Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456070, here are decompositions:

3 + 31456067 = 31456070
67 + 31456003 = 31456070
109 + 31455961 = 31456070
181 + 31455889 = 31456070
193 + 31455877 = 31456070
211 + 31455859 = 31456070
229 + 31455841 = 31456070
241 + 31455829 = 31456070

Showing the first eight; more decompositions exist.
