Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491100, here are decompositions:

37 + 33491063 = 33491100
43 + 33491057 = 33491100
59 + 33491041 = 33491100
101 + 33490999 = 33491100
103 + 33490997 = 33491100
109 + 33490991 = 33491100
113 + 33490987 = 33491100
151 + 33490949 = 33491100

Showing the first eight; more decompositions exist.
