Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33531880, here are decompositions:

3 + 33531877 = 33531880
89 + 33531791 = 33531880
131 + 33531749 = 33531880
227 + 33531653 = 33531880
269 + 33531611 = 33531880
293 + 33531587 = 33531880
353 + 33531527 = 33531880
401 + 33531479 = 33531880

Showing the first eight; more decompositions exist.
