Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33494720, here are decompositions:

37 + 33494683 = 33494720
43 + 33494677 = 33494720
109 + 33494611 = 33494720
163 + 33494557 = 33494720
223 + 33494497 = 33494720
241 + 33494479 = 33494720
313 + 33494407 = 33494720
373 + 33494347 = 33494720

Showing the first eight; more decompositions exist.
