Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169500, here are decompositions:

7 + 169493 = 169500
11 + 169489 = 169500
17 + 169483 = 169500
29 + 169471 = 169500
43 + 169457 = 169500
73 + 169427 = 169500
101 + 169399 = 169500
127 + 169373 = 169500

Showing the first eight; more decompositions exist.
