Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491730, here are decompositions:

11 + 33491719 = 33491730
17 + 33491713 = 33491730
37 + 33491693 = 33491730
59 + 33491671 = 33491730
89 + 33491641 = 33491730
109 + 33491621 = 33491730
127 + 33491603 = 33491730
131 + 33491599 = 33491730

Showing the first eight; more decompositions exist.
