Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126204, here are decompositions:

5 + 126199 = 126204
31 + 126173 = 126204
53 + 126151 = 126204
61 + 126143 = 126204
73 + 126131 = 126204
97 + 126107 = 126204
107 + 126097 = 126204
137 + 126067 = 126204

Showing the first eight; more decompositions exist.
