Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561242, here are decompositions:

61 + 33561181 = 33561242
73 + 33561169 = 33561242
103 + 33561139 = 33561242
139 + 33561103 = 33561242
163 + 33561079 = 33561242
223 + 33561019 = 33561242
229 + 33561013 = 33561242
313 + 33560929 = 33561242

Showing the first eight; more decompositions exist.
