Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527492, here are decompositions:

11 + 31527481 = 31527492
79 + 31527413 = 31527492
103 + 31527389 = 31527492
149 + 31527343 = 31527492
181 + 31527311 = 31527492
239 + 31527253 = 31527492
281 + 31527211 = 31527492
349 + 31527143 = 31527492

Showing the first eight; more decompositions exist.
