Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616944, here are decompositions:

11 + 31616933 = 31616944
41 + 31616903 = 31616944
53 + 31616891 = 31616944
197 + 31616747 = 31616944
251 + 31616693 = 31616944
257 + 31616687 = 31616944
383 + 31616561 = 31616944
521 + 31616423 = 31616944

Showing the first eight; more decompositions exist.
