Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561878, here are decompositions:

61 + 33561817 = 33561878
79 + 33561799 = 33561878
109 + 33561769 = 33561878
127 + 33561751 = 33561878
199 + 33561679 = 33561878
271 + 33561607 = 33561878
307 + 33561571 = 33561878
409 + 33561469 = 33561878

Showing the first eight; more decompositions exist.
