Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531398, here are decompositions:

7 + 33531391 = 33531398
79 + 33531319 = 33531398
151 + 33531247 = 33531398
211 + 33531187 = 33531398
337 + 33531061 = 33531398
349 + 33531049 = 33531398
367 + 33531031 = 33531398
379 + 33531019 = 33531398

Showing the first eight; more decompositions exist.
