Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581256, here are decompositions:

47 + 33581209 = 33581256
109 + 33581147 = 33581256
139 + 33581117 = 33581256
157 + 33581099 = 33581256
229 + 33581027 = 33581256
263 + 33580993 = 33581256
337 + 33580919 = 33581256
347 + 33580909 = 33581256

Showing the first eight; more decompositions exist.
