Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616584, here are decompositions:

5 + 31616579 = 31616584
23 + 31616561 = 31616584
173 + 31616411 = 31616584
191 + 31616393 = 31616584
257 + 31616327 = 31616584
353 + 31616231 = 31616584
401 + 31616183 = 31616584
563 + 31616021 = 31616584

Showing the first eight; more decompositions exist.
