Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617234, here are decompositions:

53 + 31617181 = 31617234
67 + 31617167 = 31617234
101 + 31617133 = 31617234
157 + 31617077 = 31617234
211 + 31617023 = 31617234
223 + 31617011 = 31617234
283 + 31616951 = 31617234
317 + 31616917 = 31617234

Showing the first eight; more decompositions exist.
