Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547482, here are decompositions:

3 + 31547479 = 31547482
11 + 31547471 = 31547482
23 + 31547459 = 31547482
41 + 31547441 = 31547482
179 + 31547303 = 31547482
251 + 31547231 = 31547482
353 + 31547129 = 31547482
389 + 31547093 = 31547482

Showing the first eight; more decompositions exist.
