Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484270, here are decompositions:

3 + 31484267 = 31484270
31 + 31484239 = 31484270
61 + 31484209 = 31484270
67 + 31484203 = 31484270
109 + 31484161 = 31484270
127 + 31484143 = 31484270
199 + 31484071 = 31484270
211 + 31484059 = 31484270

Showing the first eight; more decompositions exist.
