Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551672, here are decompositions:

43 + 33551629 = 33551672
79 + 33551593 = 33551672
139 + 33551533 = 33551672
163 + 33551509 = 33551672
211 + 33551461 = 33551672
223 + 33551449 = 33551672
373 + 33551299 = 33551672
463 + 33551209 = 33551672

Showing the first eight; more decompositions exist.
