Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480052, here are decompositions:

3 + 31480049 = 31480052
31 + 31480021 = 31480052
103 + 31479949 = 31480052
223 + 31479829 = 31480052
283 + 31479769 = 31480052
313 + 31479739 = 31480052
433 + 31479619 = 31480052
463 + 31479589 = 31480052

Showing the first eight; more decompositions exist.
