Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626874, here are decompositions:

5 + 31626869 = 31626874
17 + 31626857 = 31626874
47 + 31626827 = 31626874
107 + 31626767 = 31626874
311 + 31626563 = 31626874
317 + 31626557 = 31626874
467 + 31626407 = 31626874
491 + 31626383 = 31626874

Showing the first eight; more decompositions exist.
