Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518840, here are decompositions:

7 + 33518833 = 33518840
73 + 33518767 = 33518840
109 + 33518731 = 33518840
163 + 33518677 = 33518840
349 + 33518491 = 33518840
547 + 33518293 = 33518840
571 + 33518269 = 33518840
601 + 33518239 = 33518840

Showing the first eight; more decompositions exist.
