Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470234, here are decompositions:

11 + 31470223 = 31470234
13 + 31470221 = 31470234
17 + 31470217 = 31470234
41 + 31470193 = 31470234
67 + 31470167 = 31470234
83 + 31470151 = 31470234
137 + 31470097 = 31470234
167 + 31470067 = 31470234

Showing the first eight; more decompositions exist.
