Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551642, here are decompositions:

13 + 33551629 = 33551642
109 + 33551533 = 33551642
181 + 33551461 = 33551642
193 + 33551449 = 33551642
433 + 33551209 = 33551642
463 + 33551179 = 33551642
601 + 33551041 = 33551642
661 + 33550981 = 33551642

Showing the first eight; more decompositions exist.
