Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491138, here are decompositions:

97 + 33491041 = 33491138
139 + 33490999 = 33491138
151 + 33490987 = 33491138
157 + 33490981 = 33491138
211 + 33490927 = 33491138
337 + 33490801 = 33491138
601 + 33490537 = 33491138
619 + 33490519 = 33491138

Showing the first eight; more decompositions exist.
