Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531540, here are decompositions:

13 + 33531527 = 33531540
37 + 33531503 = 33531540
41 + 33531499 = 33531540
61 + 33531479 = 33531540
67 + 33531473 = 33531540
71 + 33531469 = 33531540
73 + 33531467 = 33531540
89 + 33531451 = 33531540

Showing the first eight; more decompositions exist.
