Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618740, here are decompositions:

3 + 33618737 = 33618740
97 + 33618643 = 33618740
163 + 33618577 = 33618740
409 + 33618331 = 33618740
433 + 33618307 = 33618740
541 + 33618199 = 33618740
601 + 33618139 = 33618740
709 + 33618031 = 33618740

Showing the first eight; more decompositions exist.
