Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616392, here are decompositions:

11 + 31616381 = 31616392
23 + 31616369 = 31616392
29 + 31616363 = 31616392
53 + 31616339 = 31616392
131 + 31616261 = 31616392
173 + 31616219 = 31616392
263 + 31616129 = 31616392
359 + 31616033 = 31616392

Showing the first eight; more decompositions exist.
