Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470276, here are decompositions:

17 + 31470259 = 31470276
53 + 31470223 = 31470276
59 + 31470217 = 31470276
67 + 31470209 = 31470276
83 + 31470193 = 31470276
109 + 31470167 = 31470276
179 + 31470097 = 31470276
239 + 31470037 = 31470276

Showing the first eight; more decompositions exist.
