Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515380, here are decompositions:

11 + 33515369 = 33515380
23 + 33515357 = 33515380
47 + 33515333 = 33515380
113 + 33515267 = 33515380
137 + 33515243 = 33515380
149 + 33515231 = 33515380
251 + 33515129 = 33515380
281 + 33515099 = 33515380

Showing the first eight; more decompositions exist.
