Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025206, here are decompositions:

3 + 1025203 = 1025206
53 + 1025153 = 1025206
59 + 1025147 = 1025206
107 + 1025099 = 1025206
113 + 1025093 = 1025206
167 + 1025039 = 1025206
197 + 1025009 = 1025206
263 + 1024943 = 1025206

Showing the first eight; more decompositions exist.
