Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556380, here are decompositions:

19 + 33556361 = 33556380
23 + 33556357 = 33556380
37 + 33556343 = 33556380
41 + 33556339 = 33556380
79 + 33556301 = 33556380
149 + 33556231 = 33556380
173 + 33556207 = 33556380
191 + 33556189 = 33556380

Showing the first eight; more decompositions exist.
