Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487818, here are decompositions:

5 + 33487813 = 33487818
47 + 33487771 = 33487818
59 + 33487759 = 33487818
61 + 33487757 = 33487818
101 + 33487717 = 33487818
137 + 33487681 = 33487818
167 + 33487651 = 33487818
179 + 33487639 = 33487818

Showing the first eight; more decompositions exist.
