Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482214, here are decompositions:

41 + 31482173 = 31482214
47 + 31482167 = 31482214
131 + 31482083 = 31482214
167 + 31482047 = 31482214
173 + 31482041 = 31482214
233 + 31481981 = 31482214
263 + 31481951 = 31482214
293 + 31481921 = 31482214

Showing the first eight; more decompositions exist.
