Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538242, here are decompositions:

41 + 538201 = 538242
43 + 538199 = 538242
79 + 538163 = 538242
83 + 538159 = 538242
149 + 538093 = 538242
163 + 538079 = 538242
191 + 538051 = 538242
193 + 538049 = 538242

Showing the first eight; more decompositions exist.
