Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518988, here are decompositions:

11 + 33518977 = 33518988
47 + 33518941 = 33518988
67 + 33518921 = 33518988
79 + 33518909 = 33518988
127 + 33518861 = 33518988
257 + 33518731 = 33518988
311 + 33518677 = 33518988
337 + 33518651 = 33518988

Showing the first eight; more decompositions exist.
