Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33494940, here are decompositions:

13 + 33494927 = 33494940
19 + 33494921 = 33494940
43 + 33494897 = 33494940
79 + 33494861 = 33494940
103 + 33494837 = 33494940
107 + 33494833 = 33494940
137 + 33494803 = 33494940
151 + 33494789 = 33494940

Showing the first eight; more decompositions exist.
