Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531912, here are decompositions:

23 + 33531889 = 33531912
59 + 33531853 = 33531912
131 + 33531781 = 33531912
163 + 33531749 = 33531912
233 + 33531679 = 33531912
241 + 33531671 = 33531912
251 + 33531661 = 33531912
353 + 33531559 = 33531912

Showing the first eight; more decompositions exist.
