Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470246, here are decompositions:

23 + 31470223 = 31470246
29 + 31470217 = 31470246
37 + 31470209 = 31470246
47 + 31470199 = 31470246
53 + 31470193 = 31470246
79 + 31470167 = 31470246
103 + 31470143 = 31470246
149 + 31470097 = 31470246

Showing the first eight; more decompositions exist.
