Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493940, here are decompositions:

19 + 33493921 = 33493940
127 + 33493813 = 33493940
157 + 33493783 = 33493940
163 + 33493777 = 33493940
223 + 33493717 = 33493940
313 + 33493627 = 33493940
349 + 33493591 = 33493940
367 + 33493573 = 33493940

Showing the first eight; more decompositions exist.
