Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484658, here are decompositions:

11 + 31484647 = 31484658
31 + 31484627 = 31484658
41 + 31484617 = 31484658
89 + 31484569 = 31484658
197 + 31484461 = 31484658
241 + 31484417 = 31484658
281 + 31484377 = 31484658
419 + 31484239 = 31484658

Showing the first eight; more decompositions exist.
