Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527406, here are decompositions:

17 + 31527389 = 31527406
83 + 31527323 = 31527406
89 + 31527317 = 31527406
173 + 31527233 = 31527406
233 + 31527173 = 31527406
257 + 31527149 = 31527406
263 + 31527143 = 31527406
359 + 31527047 = 31527406

Showing the first eight; more decompositions exist.
