Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616452, here are decompositions:

29 + 31616423 = 31616452
41 + 31616411 = 31616452
59 + 31616393 = 31616452
71 + 31616381 = 31616452
83 + 31616369 = 31616452
89 + 31616363 = 31616452
113 + 31616339 = 31616452
191 + 31616261 = 31616452

Showing the first eight; more decompositions exist.
