Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33510972, here are decompositions:

23 + 33510949 = 33510972
59 + 33510913 = 33510972
71 + 33510901 = 33510972
139 + 33510833 = 33510972
151 + 33510821 = 33510972
191 + 33510781 = 33510972
193 + 33510779 = 33510972
223 + 33510749 = 33510972

Showing the first eight; more decompositions exist.
