Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518788, here are decompositions:

5 + 33518783 = 33518788
137 + 33518651 = 33518788
167 + 33518621 = 33518788
179 + 33518609 = 33518788
197 + 33518591 = 33518788
461 + 33518327 = 33518788
491 + 33518297 = 33518788
521 + 33518267 = 33518788

Showing the first eight; more decompositions exist.
