Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489990, here are decompositions:

11 + 33489979 = 33489990
13 + 33489977 = 33489990
29 + 33489961 = 33489990
43 + 33489947 = 33489990
47 + 33489943 = 33489990
59 + 33489931 = 33489990
89 + 33489901 = 33489990
113 + 33489877 = 33489990

Showing the first eight; more decompositions exist.
