Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496420, here are decompositions:

3 + 31496417 = 31496420
31 + 31496389 = 31496420
103 + 31496317 = 31496420
127 + 31496293 = 31496420
157 + 31496263 = 31496420
199 + 31496221 = 31496420
211 + 31496209 = 31496420
337 + 31496083 = 31496420

Showing the first eight; more decompositions exist.
