Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542778, here are decompositions:

19 + 33542759 = 33542778
29 + 33542749 = 33542778
41 + 33542737 = 33542778
67 + 33542711 = 33542778
167 + 33542611 = 33542778
211 + 33542567 = 33542778
239 + 33542539 = 33542778
389 + 33542389 = 33542778

Showing the first eight; more decompositions exist.
