Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616372, here are decompositions:

3 + 31616369 = 31616372
13 + 31616359 = 31616372
199 + 31616173 = 31616372
223 + 31616149 = 31616372
313 + 31616059 = 31616372
331 + 31616041 = 31616372
349 + 31616023 = 31616372
373 + 31615999 = 31616372

Showing the first eight; more decompositions exist.
