Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534682, here are decompositions:

13 + 31534669 = 31534682
31 + 31534651 = 31534682
139 + 31534543 = 31534682
181 + 31534501 = 31534682
199 + 31534483 = 31534682
241 + 31534441 = 31534682
271 + 31534411 = 31534682
313 + 31534369 = 31534682

Showing the first eight; more decompositions exist.
