Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616374, here are decompositions:

5 + 31616369 = 31616374
11 + 31616363 = 31616374
47 + 31616327 = 31616374
113 + 31616261 = 31616374
191 + 31616183 = 31616374
353 + 31616021 = 31616374
401 + 31615973 = 31616374
617 + 31615757 = 31616374

Showing the first eight; more decompositions exist.
