Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493920, here are decompositions:

7 + 33493913 = 33493920
13 + 33493907 = 33493920
29 + 33493891 = 33493920
43 + 33493877 = 33493920
79 + 33493841 = 33493920
107 + 33493813 = 33493920
113 + 33493807 = 33493920
137 + 33493783 = 33493920

Showing the first eight; more decompositions exist.
