Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531812, here are decompositions:

19 + 33531793 = 33531812
31 + 33531781 = 33531812
151 + 33531661 = 33531812
199 + 33531613 = 33531812
271 + 33531541 = 33531812
313 + 33531499 = 33531812
373 + 33531439 = 33531812
409 + 33531403 = 33531812

Showing the first eight; more decompositions exist.
