Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488920, here are decompositions:

29 + 33488891 = 33488920
53 + 33488867 = 33488920
83 + 33488837 = 33488920
131 + 33488789 = 33488920
149 + 33488771 = 33488920
173 + 33488747 = 33488920
191 + 33488729 = 33488920
233 + 33488687 = 33488920

Showing the first eight; more decompositions exist.
