Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581850, here are decompositions:

13 + 33581837 = 33581850
31 + 33581819 = 33581850
37 + 33581813 = 33581850
59 + 33581791 = 33581850
83 + 33581767 = 33581850
89 + 33581761 = 33581850
109 + 33581741 = 33581850
157 + 33581693 = 33581850

Showing the first eight; more decompositions exist.
