Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491740, here are decompositions:

11 + 33491729 = 33491740
47 + 33491693 = 33491740
59 + 33491681 = 33491740
101 + 33491639 = 33491740
137 + 33491603 = 33491740
173 + 33491567 = 33491740
179 + 33491561 = 33491740
197 + 33491543 = 33491740

Showing the first eight; more decompositions exist.
