Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616602, here are decompositions:

23 + 31616579 = 31616602
41 + 31616561 = 31616602
179 + 31616423 = 31616602
191 + 31616411 = 31616602
233 + 31616369 = 31616602
239 + 31616363 = 31616602
263 + 31616339 = 31616602
383 + 31616219 = 31616602

Showing the first eight; more decompositions exist.
