Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531890, here are decompositions:

3 + 33531887 = 33531890
13 + 33531877 = 33531890
37 + 33531853 = 33531890
43 + 33531847 = 33531890
97 + 33531793 = 33531890
109 + 33531781 = 33531890
211 + 33531679 = 33531890
229 + 33531661 = 33531890

Showing the first eight; more decompositions exist.
