Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470296, here are decompositions:

3 + 31470293 = 31470296
37 + 31470259 = 31470296
73 + 31470223 = 31470296
79 + 31470217 = 31470296
97 + 31470199 = 31470296
103 + 31470193 = 31470296
199 + 31470097 = 31470296
223 + 31470073 = 31470296

Showing the first eight; more decompositions exist.
