Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617302, here are decompositions:

19 + 31617283 = 31617302
103 + 31617199 = 31617302
229 + 31617073 = 31617302
373 + 31616929 = 31617302
463 + 31616839 = 31617302
631 + 31616671 = 31617302
733 + 31616569 = 31617302
823 + 31616479 = 31617302

Showing the first eight; more decompositions exist.
