Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470354, here are decompositions:

17 + 31470337 = 31470354
31 + 31470323 = 31470354
61 + 31470293 = 31470354
131 + 31470223 = 31470354
137 + 31470217 = 31470354
211 + 31470143 = 31470354
257 + 31470097 = 31470354
281 + 31470073 = 31470354

Showing the first eight; more decompositions exist.
