Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621242, here are decompositions:

73 + 33621169 = 33621242
79 + 33621163 = 33621242
211 + 33621031 = 33621242
283 + 33620959 = 33621242
313 + 33620929 = 33621242
331 + 33620911 = 33621242
433 + 33620809 = 33621242
439 + 33620803 = 33621242

Showing the first eight; more decompositions exist.
