Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582052, here are decompositions:

3 + 31582049 = 31582052
31 + 31582021 = 31582052
79 + 31581973 = 31582052
163 + 31581889 = 31582052
193 + 31581859 = 31582052
373 + 31581679 = 31582052
379 + 31581673 = 31582052
409 + 31581643 = 31582052

Showing the first eight; more decompositions exist.
