Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33545900, here are decompositions:

61 + 33545839 = 33545900
97 + 33545803 = 33545900
277 + 33545623 = 33545900
373 + 33545527 = 33545900
457 + 33545443 = 33545900
499 + 33545401 = 33545900
523 + 33545377 = 33545900
571 + 33545329 = 33545900

Showing the first eight; more decompositions exist.
