Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456068, here are decompositions:

47 + 31456021 = 31456068
107 + 31455961 = 31456068
109 + 31455959 = 31456068
139 + 31455929 = 31456068
167 + 31455901 = 31456068
179 + 31455889 = 31456068
191 + 31455877 = 31456068
199 + 31455869 = 31456068

Showing the first eight; more decompositions exist.
