Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616108, here are decompositions:

61 + 31616047 = 31616108
67 + 31616041 = 31616108
109 + 31615999 = 31616108
157 + 31615951 = 31616108
367 + 31615741 = 31616108
379 + 31615729 = 31616108
397 + 31615711 = 31616108
439 + 31615669 = 31616108

Showing the first eight; more decompositions exist.
