Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527346, here are decompositions:

3 + 31527343 = 31527346
23 + 31527323 = 31527346
29 + 31527317 = 31527346
113 + 31527233 = 31527346
173 + 31527173 = 31527346
197 + 31527149 = 31527346
239 + 31527107 = 31527346
269 + 31527077 = 31527346

Showing the first eight; more decompositions exist.
