Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33572186, here are decompositions:

13 + 33572173 = 33572186
103 + 33572083 = 33572186
157 + 33572029 = 33572186
223 + 33571963 = 33572186
313 + 33571873 = 33572186
337 + 33571849 = 33572186
367 + 33571819 = 33572186
379 + 33571807 = 33572186

Showing the first eight; more decompositions exist.
