Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496222, here are decompositions:

3 + 31496219 = 31496222
13 + 31496209 = 31496222
61 + 31496161 = 31496222
103 + 31496119 = 31496222
139 + 31496083 = 31496222
181 + 31496041 = 31496222
211 + 31496011 = 31496222
421 + 31495801 = 31496222

Showing the first eight; more decompositions exist.
