Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105202, here are decompositions:

3 + 105199 = 105202
29 + 105173 = 105202
59 + 105143 = 105202
131 + 105071 = 105202
179 + 105023 = 105202
269 + 104933 = 105202
311 + 104891 = 105202
353 + 104849 = 105202

Showing the first eight; more decompositions exist.
