Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621398, here are decompositions:

37 + 33621361 = 33621398
229 + 33621169 = 33621398
331 + 33621067 = 33621398
367 + 33621031 = 33621398
439 + 33620959 = 33621398
487 + 33620911 = 33621398
541 + 33620857 = 33621398
631 + 33620767 = 33621398

Showing the first eight; more decompositions exist.
