Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518120, here are decompositions:

73 + 33518047 = 33518120
109 + 33518011 = 33518120
199 + 33517921 = 33518120
241 + 33517879 = 33518120
271 + 33517849 = 33518120
367 + 33517753 = 33518120
373 + 33517747 = 33518120
379 + 33517741 = 33518120

Showing the first eight; more decompositions exist.
