Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537644, here are decompositions:

31 + 33537613 = 33537644
73 + 33537571 = 33537644
103 + 33537541 = 33537644
211 + 33537433 = 33537644
331 + 33537313 = 33537644
457 + 33537187 = 33537644
523 + 33537121 = 33537644
541 + 33537103 = 33537644

Showing the first eight; more decompositions exist.
