Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503440, here are decompositions:

11 + 33503429 = 33503440
29 + 33503411 = 33503440
41 + 33503399 = 33503440
71 + 33503369 = 33503440
83 + 33503357 = 33503440
107 + 33503333 = 33503440
239 + 33503201 = 33503440
263 + 33503177 = 33503440

Showing the first eight; more decompositions exist.
