Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617002, here are decompositions:

3 + 31616999 = 31617002
73 + 31616929 = 31617002
163 + 31616839 = 31617002
229 + 31616773 = 31617002
331 + 31616671 = 31617002
379 + 31616623 = 31617002
433 + 31616569 = 31617002
463 + 31616539 = 31617002

Showing the first eight; more decompositions exist.
