Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33520370, here are decompositions:

3 + 33520367 = 33520370
7 + 33520363 = 33520370
67 + 33520303 = 33520370
97 + 33520273 = 33520370
139 + 33520231 = 33520370
151 + 33520219 = 33520370
223 + 33520147 = 33520370
241 + 33520129 = 33520370

Showing the first eight; more decompositions exist.
