Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616292, here are decompositions:

5 + 31616287 = 31616292
11 + 31616281 = 31616292
31 + 31616261 = 31616292
41 + 31616251 = 31616292
61 + 31616231 = 31616292
73 + 31616219 = 31616292
109 + 31616183 = 31616292
163 + 31616129 = 31616292

Showing the first eight; more decompositions exist.
