Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617028, here are decompositions:

5 + 31617023 = 31617028
17 + 31617011 = 31617028
29 + 31616999 = 31617028
41 + 31616987 = 31617028
137 + 31616891 = 31617028
281 + 31616747 = 31617028
449 + 31616579 = 31617028
467 + 31616561 = 31617028

Showing the first eight; more decompositions exist.
