Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616632, here are decompositions:

29 + 31616603 = 31616632
53 + 31616579 = 31616632
71 + 31616561 = 31616632
239 + 31616393 = 31616632
251 + 31616381 = 31616632
263 + 31616369 = 31616632
269 + 31616363 = 31616632
293 + 31616339 = 31616632

Showing the first eight; more decompositions exist.
