Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552328, here are decompositions:

19 + 31552309 = 31552328
271 + 31552057 = 31552328
331 + 31551997 = 31552328
349 + 31551979 = 31552328
547 + 31551781 = 31552328
571 + 31551757 = 31552328
607 + 31551721 = 31552328
751 + 31551577 = 31552328

Showing the first eight; more decompositions exist.
