Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169488, here are decompositions:

5 + 169483 = 169488
17 + 169471 = 169488
31 + 169457 = 169488
61 + 169427 = 169488
79 + 169409 = 169488
89 + 169399 = 169488
127 + 169361 = 169488
149 + 169339 = 169488

Showing the first eight; more decompositions exist.
