Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456082, here are decompositions:

3 + 31456079 = 31456082
61 + 31456021 = 31456082
79 + 31456003 = 31456082
181 + 31455901 = 31456082
193 + 31455889 = 31456082
223 + 31455859 = 31456082
241 + 31455841 = 31456082
331 + 31455751 = 31456082

Showing the first eight; more decompositions exist.
