Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616430, here are decompositions:

7 + 31616423 = 31616430
11 + 31616419 = 31616430
19 + 31616411 = 31616430
29 + 31616401 = 31616430
37 + 31616393 = 31616430
61 + 31616369 = 31616430
67 + 31616363 = 31616430
71 + 31616359 = 31616430

Showing the first eight; more decompositions exist.
