Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581672, here are decompositions:

73 + 33581599 = 33581672
151 + 33581521 = 33581672
181 + 33581491 = 33581672
373 + 33581299 = 33581672
409 + 33581263 = 33581672
463 + 33581209 = 33581672
541 + 33581131 = 33581672
661 + 33581011 = 33581672

Showing the first eight; more decompositions exist.
