Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561872, here are decompositions:

73 + 33561799 = 33561872
103 + 33561769 = 33561872
193 + 33561679 = 33561872
199 + 33561673 = 33561872
313 + 33561559 = 33561872
601 + 33561271 = 33561872
691 + 33561181 = 33561872
733 + 33561139 = 33561872

Showing the first eight; more decompositions exist.
