Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531572, here are decompositions:

13 + 33531559 = 33531572
31 + 33531541 = 33531572
73 + 33531499 = 33531572
103 + 33531469 = 33531572
181 + 33531391 = 33531572
223 + 33531349 = 33531572
523 + 33531049 = 33531572
541 + 33531031 = 33531572

Showing the first eight; more decompositions exist.
