Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470342, here are decompositions:

5 + 31470337 = 31470342
19 + 31470323 = 31470342
83 + 31470259 = 31470342
149 + 31470193 = 31470342
191 + 31470151 = 31470342
199 + 31470143 = 31470342
269 + 31470073 = 31470342
353 + 31469989 = 31470342

Showing the first eight; more decompositions exist.
