Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616782, here are decompositions:

53 + 31616729 = 31616782
89 + 31616693 = 31616782
179 + 31616603 = 31616782
359 + 31616423 = 31616782
389 + 31616393 = 31616782
401 + 31616381 = 31616782
419 + 31616363 = 31616782
443 + 31616339 = 31616782

Showing the first eight; more decompositions exist.
