Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491720, here are decompositions:

7 + 33491713 = 33491720
79 + 33491641 = 33491720
127 + 33491593 = 33491720
151 + 33491569 = 33491720
349 + 33491371 = 33491720
487 + 33491233 = 33491720
499 + 33491221 = 33491720
571 + 33491149 = 33491720

Showing the first eight; more decompositions exist.
