Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169210, here are decompositions:

11 + 169199 = 169210
29 + 169181 = 169210
59 + 169151 = 169210
113 + 169097 = 169210
131 + 169079 = 169210
191 + 169019 = 169210
233 + 168977 = 169210
311 + 168899 = 169210

Showing the first eight; more decompositions exist.
