Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481812, here are decompositions:

5 + 33481807 = 33481812
11 + 33481801 = 33481812
29 + 33481783 = 33481812
43 + 33481769 = 33481812
53 + 33481759 = 33481812
59 + 33481753 = 33481812
61 + 33481751 = 33481812
73 + 33481739 = 33481812

Showing the first eight; more decompositions exist.
