Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458152, here are decompositions:

139 + 31458013 = 31458152
163 + 31457989 = 31458152
223 + 31457929 = 31458152
241 + 31457911 = 31458152
283 + 31457869 = 31458152
331 + 31457821 = 31458152
409 + 31457743 = 31458152
433 + 31457719 = 31458152

Showing the first eight; more decompositions exist.
