Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491540, here are decompositions:

3 + 33491537 = 33491540
7 + 33491533 = 33491540
73 + 33491467 = 33491540
79 + 33491461 = 33491540
307 + 33491233 = 33491540
337 + 33491203 = 33491540
499 + 33491041 = 33491540
541 + 33490999 = 33491540

Showing the first eight; more decompositions exist.
