Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621148, here are decompositions:

101 + 33621047 = 33621148
149 + 33620999 = 33621148
257 + 33620891 = 33621148
359 + 33620789 = 33621148
467 + 33620681 = 33621148
521 + 33620627 = 33621148
557 + 33620591 = 33621148
569 + 33620579 = 33621148

Showing the first eight; more decompositions exist.
