Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621554, here are decompositions:

13 + 33621541 = 33621554
157 + 33621397 = 33621554
193 + 33621361 = 33621554
271 + 33621283 = 33621554
487 + 33621067 = 33621554
523 + 33621031 = 33621554
643 + 33620911 = 33621554
751 + 33620803 = 33621554

Showing the first eight; more decompositions exist.
