Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617104, here are decompositions:

3 + 31617101 = 31617104
31 + 31617073 = 31617104
331 + 31616773 = 31617104
397 + 31616707 = 31617104
433 + 31616671 = 31617104
457 + 31616647 = 31617104
823 + 31616281 = 31617104
853 + 31616251 = 31617104

Showing the first eight; more decompositions exist.
