Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494584, here are decompositions:

3 + 31494581 = 31494584
31 + 31494553 = 31494584
157 + 31494427 = 31494584
283 + 31494301 = 31494584
337 + 31494247 = 31494584
487 + 31494097 = 31494584
601 + 31493983 = 31494584
643 + 31493941 = 31494584

Showing the first eight; more decompositions exist.
