Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478740, here are decompositions:

13 + 33478727 = 33478740
17 + 33478723 = 33478740
19 + 33478721 = 33478740
47 + 33478693 = 33478740
59 + 33478681 = 33478740
89 + 33478651 = 33478740
131 + 33478609 = 33478740
157 + 33478583 = 33478740

Showing the first eight; more decompositions exist.
