Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484766, here are decompositions:

13 + 31484753 = 31484766
67 + 31484699 = 31484766
139 + 31484627 = 31484766
149 + 31484617 = 31484766
197 + 31484569 = 31484766
223 + 31484543 = 31484766
233 + 31484533 = 31484766
263 + 31484503 = 31484766

Showing the first eight; more decompositions exist.
