Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553852, here are decompositions:

19 + 31553833 = 31553852
181 + 31553671 = 31553852
193 + 31553659 = 31553852
349 + 31553503 = 31553852
619 + 31553233 = 31553852
691 + 31553161 = 31553852
853 + 31552999 = 31553852
1021 + 31552831 = 31553852

Showing the first eight; more decompositions exist.
