Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491142, here are decompositions:

31 + 33491111 = 33491142
43 + 33491099 = 33491142
79 + 33491063 = 33491142
101 + 33491041 = 33491142
151 + 33490991 = 33491142
193 + 33490949 = 33491142
379 + 33490763 = 33491142
449 + 33490693 = 33491142

Showing the first eight; more decompositions exist.
