Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617350, here are decompositions:

67 + 31617283 = 31617350
97 + 31617253 = 31617350
151 + 31617199 = 31617350
277 + 31617073 = 31617350
337 + 31617013 = 31617350
421 + 31616929 = 31617350
433 + 31616917 = 31617350
463 + 31616887 = 31617350

Showing the first eight; more decompositions exist.
