Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620056, here are decompositions:

19 + 31620037 = 31620056
37 + 31620019 = 31620056
43 + 31620013 = 31620056
67 + 31619989 = 31620056
103 + 31619953 = 31620056
373 + 31619683 = 31620056
409 + 31619647 = 31620056
439 + 31619617 = 31620056

Showing the first eight; more decompositions exist.
