Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484610, here are decompositions:

41 + 31484569 = 31484610
67 + 31484543 = 31484610
97 + 31484513 = 31484610
107 + 31484503 = 31484610
149 + 31484461 = 31484610
193 + 31484417 = 31484610
197 + 31484413 = 31484610
233 + 31484377 = 31484610

Showing the first eight; more decompositions exist.
