Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578142, here are decompositions:

11 + 33578131 = 33578142
23 + 33578119 = 33578142
43 + 33578099 = 33578142
131 + 33578011 = 33578142
139 + 33578003 = 33578142
163 + 33577979 = 33578142
223 + 33577919 = 33578142
233 + 33577909 = 33578142

Showing the first eight; more decompositions exist.
