Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531800, here are decompositions:

7 + 33531793 = 33531800
19 + 33531781 = 33531800
139 + 33531661 = 33531800
223 + 33531577 = 33531800
241 + 33531559 = 33531800
331 + 33531469 = 33531800
349 + 33531451 = 33531800
373 + 33531427 = 33531800

Showing the first eight; more decompositions exist.
