Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33490860, here are decompositions:

17 + 33490843 = 33490860
19 + 33490841 = 33490860
43 + 33490817 = 33490860
47 + 33490813 = 33490860
59 + 33490801 = 33490860
79 + 33490781 = 33490860
83 + 33490777 = 33490860
97 + 33490763 = 33490860

Showing the first eight; more decompositions exist.
