Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616322, here are decompositions:

41 + 31616281 = 31616322
61 + 31616261 = 31616322
71 + 31616251 = 31616322
103 + 31616219 = 31616322
139 + 31616183 = 31616322
149 + 31616173 = 31616322
173 + 31616149 = 31616322
193 + 31616129 = 31616322

Showing the first eight; more decompositions exist.
