Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616370, here are decompositions:

7 + 31616363 = 31616370
11 + 31616359 = 31616370
31 + 31616339 = 31616370
43 + 31616327 = 31616370
73 + 31616297 = 31616370
83 + 31616287 = 31616370
89 + 31616281 = 31616370
109 + 31616261 = 31616370

Showing the first eight; more decompositions exist.
