Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470326, here are decompositions:

3 + 31470323 = 31470326
67 + 31470259 = 31470326
103 + 31470223 = 31470326
109 + 31470217 = 31470326
127 + 31470199 = 31470326
229 + 31470097 = 31470326
313 + 31470013 = 31470326
337 + 31469989 = 31470326

Showing the first eight; more decompositions exist.
