Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507580, here are decompositions:

3 + 33507577 = 33507580
17 + 33507563 = 33507580
137 + 33507443 = 33507580
167 + 33507413 = 33507580
173 + 33507407 = 33507580
179 + 33507401 = 33507580
233 + 33507347 = 33507580
443 + 33507137 = 33507580

Showing the first eight; more decompositions exist.
