Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621248, here are decompositions:

79 + 33621169 = 33621248
139 + 33621109 = 33621248
181 + 33621067 = 33621248
211 + 33621037 = 33621248
337 + 33620911 = 33621248
439 + 33620809 = 33621248
487 + 33620761 = 33621248
499 + 33620749 = 33621248

Showing the first eight; more decompositions exist.
