Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488140, here are decompositions:

3 + 33488137 = 33488140
17 + 33488123 = 33488140
53 + 33488087 = 33488140
107 + 33488033 = 33488140
137 + 33488003 = 33488140
167 + 33487973 = 33488140
227 + 33487913 = 33488140
233 + 33487907 = 33488140

Showing the first eight; more decompositions exist.
