Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482374, here are decompositions:

31 + 31482343 = 31482374
37 + 31482337 = 31482374
67 + 31482307 = 31482374
97 + 31482277 = 31482374
103 + 31482271 = 31482374
127 + 31482247 = 31482374
271 + 31482103 = 31482374
277 + 31482097 = 31482374

Showing the first eight; more decompositions exist.
