Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169430, here are decompositions:

3 + 169427 = 169430
31 + 169399 = 169430
61 + 169369 = 169430
103 + 169327 = 169430
109 + 169321 = 169430
181 + 169249 = 169430
211 + 169219 = 169430
271 + 169159 = 169430

Showing the first eight; more decompositions exist.
