Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487916, here are decompositions:

3 + 33487913 = 33487916
13 + 33487903 = 33487916
97 + 33487819 = 33487916
103 + 33487813 = 33487916
157 + 33487759 = 33487916
199 + 33487717 = 33487916
277 + 33487639 = 33487916
337 + 33487579 = 33487916

Showing the first eight; more decompositions exist.
