Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487880, here are decompositions:

3 + 33487877 = 33487880
61 + 33487819 = 33487880
67 + 33487813 = 33487880
109 + 33487771 = 33487880
163 + 33487717 = 33487880
199 + 33487681 = 33487880
229 + 33487651 = 33487880
241 + 33487639 = 33487880

Showing the first eight; more decompositions exist.
