Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527498, here are decompositions:

7 + 31527491 = 31527498
17 + 31527481 = 31527498
109 + 31527389 = 31527498
181 + 31527317 = 31527498
251 + 31527247 = 31527498
307 + 31527191 = 31527498
347 + 31527151 = 31527498
349 + 31527149 = 31527498

Showing the first eight; more decompositions exist.
