Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557186, here are decompositions:

43 + 33557143 = 33557186
67 + 33557119 = 33557186
109 + 33557077 = 33557186
139 + 33557047 = 33557186
193 + 33556993 = 33557186
283 + 33556903 = 33557186
307 + 33556879 = 33557186
349 + 33556837 = 33557186

Showing the first eight; more decompositions exist.
