Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493986, here are decompositions:

13 + 33493973 = 33493986
17 + 33493969 = 33493986
23 + 33493963 = 33493986
73 + 33493913 = 33493986
79 + 33493907 = 33493986
109 + 33493877 = 33493986
157 + 33493829 = 33493986
173 + 33493813 = 33493986

Showing the first eight; more decompositions exist.
