Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456062, here are decompositions:

41 + 31456021 = 31456062
59 + 31456003 = 31456062
101 + 31455961 = 31456062
103 + 31455959 = 31456062
173 + 31455889 = 31456062
193 + 31455869 = 31456062
233 + 31455829 = 31456062
241 + 31455821 = 31456062

Showing the first eight; more decompositions exist.
