Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470534, here are decompositions:

181 + 31470353 = 31470534
197 + 31470337 = 31470534
211 + 31470323 = 31470534
241 + 31470293 = 31470534
311 + 31470223 = 31470534
313 + 31470221 = 31470534
317 + 31470217 = 31470534
367 + 31470167 = 31470534

Showing the first eight; more decompositions exist.
