Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527682, here are decompositions:

5 + 31527677 = 31527682
23 + 31527659 = 31527682
113 + 31527569 = 31527682
149 + 31527533 = 31527682
191 + 31527491 = 31527682
269 + 31527413 = 31527682
293 + 31527389 = 31527682
359 + 31527323 = 31527682

Showing the first eight; more decompositions exist.
