Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616066, here are decompositions:

7 + 31616059 = 31616066
19 + 31616047 = 31616066
43 + 31616023 = 31616066
67 + 31615999 = 31616066
73 + 31615993 = 31616066
283 + 31615783 = 31616066
337 + 31615729 = 31616066
397 + 31615669 = 31616066

Showing the first eight; more decompositions exist.
