Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621500, here are decompositions:

103 + 33621397 = 33621500
139 + 33621361 = 33621500
331 + 33621169 = 33621500
337 + 33621163 = 33621500
433 + 33621067 = 33621500
463 + 33621037 = 33621500
541 + 33620959 = 33621500
571 + 33620929 = 33621500

Showing the first eight; more decompositions exist.
