Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553784, here are decompositions:

13 + 33553771 = 33553784
37 + 33553747 = 33553784
127 + 33553657 = 33553784
151 + 33553633 = 33553784
367 + 33553417 = 33553784
421 + 33553363 = 33553784
457 + 33553327 = 33553784
613 + 33553171 = 33553784

Showing the first eight; more decompositions exist.
