Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561042, here are decompositions:

19 + 33561023 = 33561042
23 + 33561019 = 33561042
29 + 33561013 = 33561042
43 + 33560999 = 33561042
59 + 33560983 = 33561042
103 + 33560939 = 33561042
113 + 33560929 = 33561042
173 + 33560869 = 33561042

Showing the first eight; more decompositions exist.
