Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616884, here are decompositions:

137 + 31616747 = 31616884
191 + 31616693 = 31616884
197 + 31616687 = 31616884
281 + 31616603 = 31616884
461 + 31616423 = 31616884
491 + 31616393 = 31616884
503 + 31616381 = 31616884
521 + 31616363 = 31616884

Showing the first eight; more decompositions exist.
