Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33544668, here are decompositions:

7 + 33544661 = 33544668
29 + 33544639 = 33544668
37 + 33544631 = 33544668
71 + 33544597 = 33544668
89 + 33544579 = 33544668
127 + 33544541 = 33544668
151 + 33544517 = 33544668
167 + 33544501 = 33544668

Showing the first eight; more decompositions exist.
