Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472872, here are decompositions:

23 + 33472849 = 33472872
89 + 33472783 = 33472872
101 + 33472771 = 33472872
113 + 33472759 = 33472872
149 + 33472723 = 33472872
179 + 33472693 = 33472872
233 + 33472639 = 33472872
269 + 33472603 = 33472872

Showing the first eight; more decompositions exist.
