Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487956, here are decompositions:

43 + 33487913 = 33487956
53 + 33487903 = 33487956
79 + 33487877 = 33487956
97 + 33487859 = 33487956
109 + 33487847 = 33487956
137 + 33487819 = 33487956
197 + 33487759 = 33487956
199 + 33487757 = 33487956

Showing the first eight; more decompositions exist.
