Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528928, here are decompositions:

19 + 31528909 = 31528928
97 + 31528831 = 31528928
127 + 31528801 = 31528928
199 + 31528729 = 31528928
307 + 31528621 = 31528928
349 + 31528579 = 31528928
397 + 31528531 = 31528928
601 + 31528327 = 31528928

Showing the first eight; more decompositions exist.
