Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581492, here are decompositions:

79 + 33581413 = 33581492
163 + 33581329 = 33581492
193 + 33581299 = 33581492
211 + 33581281 = 33581492
229 + 33581263 = 33581492
271 + 33581221 = 33581492
283 + 33581209 = 33581492
499 + 33580993 = 33581492

Showing the first eight; more decompositions exist.
