Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488128, here are decompositions:

5 + 33488123 = 33488128
41 + 33488087 = 33488128
227 + 33487901 = 33488128
251 + 33487877 = 33488128
269 + 33487859 = 33488128
281 + 33487847 = 33488128
521 + 33487607 = 33488128
617 + 33487511 = 33488128

Showing the first eight; more decompositions exist.
