Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487772, here are decompositions:

13 + 33487759 = 33487772
151 + 33487621 = 33487772
181 + 33487591 = 33487772
193 + 33487579 = 33487772
211 + 33487561 = 33487772
229 + 33487543 = 33487772
349 + 33487423 = 33487772
379 + 33487393 = 33487772

Showing the first eight; more decompositions exist.
