Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616924, here are decompositions:

7 + 31616917 = 31616924
37 + 31616887 = 31616924
67 + 31616857 = 31616924
151 + 31616773 = 31616924
277 + 31616647 = 31616924
523 + 31616401 = 31616924
643 + 31616281 = 31616924
673 + 31616251 = 31616924

Showing the first eight; more decompositions exist.
