Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617004, here are decompositions:

5 + 31616999 = 31617004
17 + 31616987 = 31617004
53 + 31616951 = 31617004
71 + 31616933 = 31617004
101 + 31616903 = 31617004
113 + 31616891 = 31617004
257 + 31616747 = 31617004
311 + 31616693 = 31617004

Showing the first eight; more decompositions exist.
