Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482348, here are decompositions:

5 + 31482343 = 31482348
11 + 31482337 = 31482348
41 + 31482307 = 31482348
67 + 31482281 = 31482348
71 + 31482277 = 31482348
101 + 31482247 = 31482348
179 + 31482169 = 31482348
181 + 31482167 = 31482348

Showing the first eight; more decompositions exist.
