Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531788, here are decompositions:

7 + 33531781 = 33531788
109 + 33531679 = 33531788
127 + 33531661 = 33531788
211 + 33531577 = 33531788
229 + 33531559 = 33531788
337 + 33531451 = 33531788
349 + 33531439 = 33531788
397 + 33531391 = 33531788

Showing the first eight; more decompositions exist.
