Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482836, here are decompositions:

3 + 31482833 = 31482836
13 + 31482823 = 31482836
37 + 31482799 = 31482836
127 + 31482709 = 31482836
193 + 31482643 = 31482836
223 + 31482613 = 31482836
277 + 31482559 = 31482836
337 + 31482499 = 31482836

Showing the first eight; more decompositions exist.
