Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616768, here are decompositions:

19 + 31616749 = 31616768
61 + 31616707 = 31616768
97 + 31616671 = 31616768
199 + 31616569 = 31616768
229 + 31616539 = 31616768
349 + 31616419 = 31616768
367 + 31616401 = 31616768
409 + 31616359 = 31616768

Showing the first eight; more decompositions exist.
