Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532762, here are decompositions:

13 + 31532749 = 31532762
103 + 31532659 = 31532762
109 + 31532653 = 31532762
181 + 31532581 = 31532762
211 + 31532551 = 31532762
223 + 31532539 = 31532762
241 + 31532521 = 31532762
409 + 31532353 = 31532762

Showing the first eight; more decompositions exist.
