Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487860, here are decompositions:

13 + 33487847 = 33487860
41 + 33487819 = 33487860
47 + 33487813 = 33487860
89 + 33487771 = 33487860
101 + 33487759 = 33487860
103 + 33487757 = 33487860
127 + 33487733 = 33487860
179 + 33487681 = 33487860

Showing the first eight; more decompositions exist.
