Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581558, here are decompositions:

37 + 33581521 = 33581558
67 + 33581491 = 33581558
229 + 33581329 = 33581558
271 + 33581287 = 33581558
277 + 33581281 = 33581558
337 + 33581221 = 33581558
349 + 33581209 = 33581558
547 + 33581011 = 33581558

Showing the first eight; more decompositions exist.
