Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33601980, here are decompositions:

29 + 33601951 = 33601980
37 + 33601943 = 33601980
59 + 33601921 = 33601980
67 + 33601913 = 33601980
79 + 33601901 = 33601980
131 + 33601849 = 33601980
149 + 33601831 = 33601980
163 + 33601817 = 33601980

Showing the first eight; more decompositions exist.
