Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616408, here are decompositions:

7 + 31616401 = 31616408
127 + 31616281 = 31616408
151 + 31616257 = 31616408
157 + 31616251 = 31616408
349 + 31616059 = 31616408
367 + 31616041 = 31616408
409 + 31615999 = 31616408
457 + 31615951 = 31616408

Showing the first eight; more decompositions exist.
