Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484650, here are decompositions:

3 + 31484647 = 31484650
23 + 31484627 = 31484650
107 + 31484543 = 31484650
137 + 31484513 = 31484650
233 + 31484417 = 31484650
311 + 31484339 = 31484650
347 + 31484303 = 31484650
383 + 31484267 = 31484650

Showing the first eight; more decompositions exist.
