Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493644, here are decompositions:

5 + 33493639 = 33493644
17 + 33493627 = 33493644
31 + 33493613 = 33493644
43 + 33493601 = 33493644
53 + 33493591 = 33493644
71 + 33493573 = 33493644
103 + 33493541 = 33493644
131 + 33493513 = 33493644

Showing the first eight; more decompositions exist.
