Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477052, here are decompositions:

31 + 31477021 = 31477052
181 + 31476871 = 31477052
199 + 31476853 = 31477052
223 + 31476829 = 31477052
349 + 31476703 = 31477052
421 + 31476631 = 31477052
601 + 31476451 = 31477052
619 + 31476433 = 31477052

Showing the first eight; more decompositions exist.
