Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531370, here are decompositions:

17 + 33531353 = 33531370
23 + 33531347 = 33531370
71 + 33531299 = 33531370
101 + 33531269 = 33531370
137 + 33531233 = 33531370
293 + 33531077 = 33531370
311 + 33531059 = 33531370
359 + 33531011 = 33531370

Showing the first eight; more decompositions exist.
