Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494282, here are decompositions:

19 + 31494263 = 31494282
41 + 31494241 = 31494282
103 + 31494179 = 31494282
139 + 31494143 = 31494282
163 + 31494119 = 31494282
191 + 31494091 = 31494282
199 + 31494083 = 31494282
229 + 31494053 = 31494282

Showing the first eight; more decompositions exist.
