Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624676, here are decompositions:

3 + 31624673 = 31624676
37 + 31624639 = 31624676
79 + 31624597 = 31624676
199 + 31624477 = 31624676
313 + 31624363 = 31624676
337 + 31624339 = 31624676
547 + 31624129 = 31624676
607 + 31624069 = 31624676

Showing the first eight; more decompositions exist.
