Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616824, here are decompositions:

131 + 31616693 = 31616824
137 + 31616687 = 31616824
263 + 31616561 = 31616824
401 + 31616423 = 31616824
431 + 31616393 = 31616824
443 + 31616381 = 31616824
461 + 31616363 = 31616824
563 + 31616261 = 31616824

Showing the first eight; more decompositions exist.
