Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616038, here are decompositions:

5 + 31616033 = 31616038
17 + 31616021 = 31616038
29 + 31616009 = 31616038
59 + 31615979 = 31616038
191 + 31615847 = 31616038
281 + 31615757 = 31616038
449 + 31615589 = 31616038
599 + 31615439 = 31616038

Showing the first eight; more decompositions exist.
