Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484652, here are decompositions:

5 + 31484647 = 31484652
83 + 31484569 = 31484652
109 + 31484543 = 31484652
139 + 31484513 = 31484652
149 + 31484503 = 31484652
191 + 31484461 = 31484652
239 + 31484413 = 31484652
293 + 31484359 = 31484652

Showing the first eight; more decompositions exist.
