Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528048, here are decompositions:

11 + 31528037 = 31528048
29 + 31528019 = 31528048
47 + 31528001 = 31528048
107 + 31527941 = 31528048
347 + 31527701 = 31528048
359 + 31527689 = 31528048
389 + 31527659 = 31528048
479 + 31527569 = 31528048

Showing the first eight; more decompositions exist.
