Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491300, here are decompositions:

67 + 33491233 = 33491300
79 + 33491221 = 33491300
97 + 33491203 = 33491300
151 + 33491149 = 33491300
313 + 33490987 = 33491300
373 + 33490927 = 33491300
457 + 33490843 = 33491300
487 + 33490813 = 33491300

Showing the first eight; more decompositions exist.
