Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521202, here are decompositions:

23 + 521179 = 521202
29 + 521173 = 521202
41 + 521161 = 521202
83 + 521119 = 521202
139 + 521063 = 521202
151 + 521051 = 521202
163 + 521039 = 521202
179 + 521023 = 521202

Showing the first eight; more decompositions exist.
