Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547660, here are decompositions:

19 + 31547641 = 31547660
31 + 31547629 = 31547660
43 + 31547617 = 31547660
103 + 31547557 = 31547660
181 + 31547479 = 31547660
211 + 31547449 = 31547660
373 + 31547287 = 31547660
379 + 31547281 = 31547660

Showing the first eight; more decompositions exist.
