Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581730, here are decompositions:

23 + 33581707 = 33581730
37 + 33581693 = 33581730
43 + 33581687 = 33581730
53 + 33581677 = 33581730
59 + 33581671 = 33581730
109 + 33581621 = 33581730
113 + 33581617 = 33581730
131 + 33581599 = 33581730

Showing the first eight; more decompositions exist.
