Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531810, here are decompositions:

17 + 33531793 = 33531810
19 + 33531791 = 33531810
29 + 33531781 = 33531810
61 + 33531749 = 33531810
73 + 33531737 = 33531810
131 + 33531679 = 33531810
139 + 33531671 = 33531810
149 + 33531661 = 33531810

Showing the first eight; more decompositions exist.
