Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581580, here are decompositions:

7 + 33581573 = 33581580
59 + 33581521 = 33581580
89 + 33581491 = 33581580
139 + 33581441 = 33581580
167 + 33581413 = 33581580
199 + 33581381 = 33581580
229 + 33581351 = 33581580
251 + 33581329 = 33581580

Showing the first eight; more decompositions exist.
