Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542890, here are decompositions:

23 + 33542867 = 33542890
89 + 33542801 = 33542890
107 + 33542783 = 33542890
113 + 33542777 = 33542890
131 + 33542759 = 33542890
137 + 33542753 = 33542890
167 + 33542723 = 33542890
179 + 33542711 = 33542890

Showing the first eight; more decompositions exist.
