Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576052, here are decompositions:

3 + 31576049 = 31576052
43 + 31576009 = 31576052
61 + 31575991 = 31576052
223 + 31575829 = 31576052
229 + 31575823 = 31576052
283 + 31575769 = 31576052
499 + 31575553 = 31576052
619 + 31575433 = 31576052

Showing the first eight; more decompositions exist.
