Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616894, here are decompositions:

3 + 31616891 = 31616894
7 + 31616887 = 31616894
37 + 31616857 = 31616894
223 + 31616671 = 31616894
271 + 31616623 = 31616894
373 + 31616521 = 31616894
607 + 31616287 = 31616894
613 + 31616281 = 31616894

Showing the first eight; more decompositions exist.
