Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491070, here are decompositions:

7 + 33491063 = 33491070
13 + 33491057 = 33491070
29 + 33491041 = 33491070
71 + 33490999 = 33491070
73 + 33490997 = 33491070
79 + 33490991 = 33491070
83 + 33490987 = 33491070
89 + 33490981 = 33491070

Showing the first eight; more decompositions exist.
