Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527402, here are decompositions:

13 + 31527389 = 31527402
59 + 31527343 = 31527402
79 + 31527323 = 31527402
149 + 31527253 = 31527402
191 + 31527211 = 31527402
211 + 31527191 = 31527402
229 + 31527173 = 31527402
251 + 31527151 = 31527402

Showing the first eight; more decompositions exist.
