Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170418, here are decompositions:

5 + 170413 = 170418
29 + 170389 = 170418
47 + 170371 = 170418
67 + 170351 = 170418
71 + 170347 = 170418
139 + 170279 = 170418
151 + 170267 = 170418
179 + 170239 = 170418

Showing the first eight; more decompositions exist.
