Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491312, here are decompositions:

79 + 33491233 = 33491312
109 + 33491203 = 33491312
163 + 33491149 = 33491312
271 + 33491041 = 33491312
313 + 33490999 = 33491312
331 + 33490981 = 33491312
499 + 33490813 = 33491312
619 + 33490693 = 33491312

Showing the first eight; more decompositions exist.
