Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481830, here are decompositions:

13 + 33481817 = 33481830
23 + 33481807 = 33481830
29 + 33481801 = 33481830
47 + 33481783 = 33481830
61 + 33481769 = 33481830
71 + 33481759 = 33481830
73 + 33481757 = 33481830
79 + 33481751 = 33481830

Showing the first eight; more decompositions exist.
