Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581542, here are decompositions:

101 + 33581441 = 33581542
131 + 33581411 = 33581542
149 + 33581393 = 33581542
191 + 33581351 = 33581542
251 + 33581291 = 33581542
263 + 33581279 = 33581542
419 + 33581123 = 33581542
443 + 33581099 = 33581542

Showing the first eight; more decompositions exist.
