Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33547940, here are decompositions:

31 + 33547909 = 33547940
67 + 33547873 = 33547940
79 + 33547861 = 33547940
109 + 33547831 = 33547940
211 + 33547729 = 33547940
313 + 33547627 = 33547940
397 + 33547543 = 33547940
523 + 33547417 = 33547940

Showing the first eight; more decompositions exist.
