Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491040, here are decompositions:

41 + 33490999 = 33491040
43 + 33490997 = 33491040
53 + 33490987 = 33491040
59 + 33490981 = 33491040
113 + 33490927 = 33491040
151 + 33490889 = 33491040
197 + 33490843 = 33491040
199 + 33490841 = 33491040

Showing the first eight; more decompositions exist.
