Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616432, here are decompositions:

13 + 31616419 = 31616432
31 + 31616401 = 31616432
73 + 31616359 = 31616432
151 + 31616281 = 31616432
181 + 31616251 = 31616432
283 + 31616149 = 31616432
373 + 31616059 = 31616432
409 + 31616023 = 31616432

Showing the first eight; more decompositions exist.
