Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470170, here are decompositions:

3 + 31470167 = 31470170
19 + 31470151 = 31470170
73 + 31470097 = 31470170
97 + 31470073 = 31470170
103 + 31470067 = 31470170
157 + 31470013 = 31470170
181 + 31469989 = 31470170
313 + 31469857 = 31470170

Showing the first eight; more decompositions exist.
