Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616662, here are decompositions:

59 + 31616603 = 31616662
83 + 31616579 = 31616662
101 + 31616561 = 31616662
239 + 31616423 = 31616662
251 + 31616411 = 31616662
269 + 31616393 = 31616662
281 + 31616381 = 31616662
293 + 31616369 = 31616662

Showing the first eight; more decompositions exist.
