Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617008, here are decompositions:

79 + 31616929 = 31617008
151 + 31616857 = 31617008
331 + 31616677 = 31617008
337 + 31616671 = 31617008
439 + 31616569 = 31617008
487 + 31616521 = 31617008
499 + 31616509 = 31617008
607 + 31616401 = 31617008

Showing the first eight; more decompositions exist.
