Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33513800, here are decompositions:

3 + 33513797 = 33513800
127 + 33513673 = 33513800
139 + 33513661 = 33513800
241 + 33513559 = 33513800
379 + 33513421 = 33513800
433 + 33513367 = 33513800
457 + 33513343 = 33513800
613 + 33513187 = 33513800

Showing the first eight; more decompositions exist.
