Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491088, here are decompositions:

31 + 33491057 = 33491088
47 + 33491041 = 33491088
89 + 33490999 = 33491088
97 + 33490991 = 33491088
101 + 33490987 = 33491088
107 + 33490981 = 33491088
139 + 33490949 = 33491088
181 + 33490907 = 33491088

Showing the first eight; more decompositions exist.
