Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617040, here are decompositions:

11 + 31617029 = 31617040
17 + 31617023 = 31617040
29 + 31617011 = 31617040
41 + 31616999 = 31617040
53 + 31616987 = 31617040
89 + 31616951 = 31617040
107 + 31616933 = 31617040
137 + 31616903 = 31617040

Showing the first eight; more decompositions exist.
