Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452482, here are decompositions:

31 + 31452451 = 31452482
181 + 31452301 = 31452482
199 + 31452283 = 31452482
241 + 31452241 = 31452482
283 + 31452199 = 31452482
421 + 31452061 = 31452482
463 + 31452019 = 31452482
601 + 31451881 = 31452482

Showing the first eight; more decompositions exist.
