Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487872, here are decompositions:

13 + 33487859 = 33487872
53 + 33487819 = 33487872
59 + 33487813 = 33487872
101 + 33487771 = 33487872
113 + 33487759 = 33487872
139 + 33487733 = 33487872
191 + 33487681 = 33487872
233 + 33487639 = 33487872

Showing the first eight; more decompositions exist.
