Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488740, here are decompositions:

11 + 33488729 = 33488740
23 + 33488717 = 33488740
53 + 33488687 = 33488740
59 + 33488681 = 33488740
71 + 33488669 = 33488740
101 + 33488639 = 33488740
113 + 33488627 = 33488740
191 + 33488549 = 33488740

Showing the first eight; more decompositions exist.
