Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617482, here are decompositions:

73 + 31617409 = 31617482
79 + 31617403 = 31617482
103 + 31617379 = 31617482
109 + 31617373 = 31617482
199 + 31617283 = 31617482
229 + 31617253 = 31617482
283 + 31617199 = 31617482
349 + 31617133 = 31617482

Showing the first eight; more decompositions exist.
