Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169470, here are decompositions:

13 + 169457 = 169470
43 + 169427 = 169470
61 + 169409 = 169470
71 + 169399 = 169470
97 + 169373 = 169470
101 + 169369 = 169470
109 + 169361 = 169470
127 + 169343 = 169470

Showing the first eight; more decompositions exist.
