Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33553730, here are decompositions:

3 + 33553727 = 33553730
37 + 33553693 = 33553730
73 + 33553657 = 33553730
79 + 33553651 = 33553730
97 + 33553633 = 33553730
181 + 33553549 = 33553730
193 + 33553537 = 33553730
211 + 33553519 = 33553730

Showing the first eight; more decompositions exist.
