Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456482, here are decompositions:

41 + 31456441 = 31456482
53 + 31456429 = 31456482
103 + 31456379 = 31456482
151 + 31456331 = 31456482
163 + 31456319 = 31456482
191 + 31456291 = 31456482
223 + 31456259 = 31456482
241 + 31456241 = 31456482

Showing the first eight; more decompositions exist.
