Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616024, here are decompositions:

3 + 31616021 = 31616024
7 + 31616017 = 31616024
31 + 31615993 = 31616024
73 + 31615951 = 31616024
103 + 31615921 = 31616024
241 + 31615783 = 31616024
283 + 31615741 = 31616024
313 + 31615711 = 31616024

Showing the first eight; more decompositions exist.
