Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170388, here are decompositions:

5 + 170383 = 170388
17 + 170371 = 170388
19 + 170369 = 170388
37 + 170351 = 170388
41 + 170347 = 170388
47 + 170341 = 170388
61 + 170327 = 170388
89 + 170299 = 170388

Showing the first eight; more decompositions exist.
