Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488730, here are decompositions:

13 + 33488717 = 33488730
43 + 33488687 = 33488730
47 + 33488683 = 33488730
61 + 33488669 = 33488730
83 + 33488647 = 33488730
103 + 33488627 = 33488730
131 + 33488599 = 33488730
137 + 33488593 = 33488730

Showing the first eight; more decompositions exist.
