Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171578, here are decompositions:

7 + 171571 = 171578
19 + 171559 = 171578
37 + 171541 = 171578
61 + 171517 = 171578
97 + 171481 = 171578
109 + 171469 = 171578
139 + 171439 = 171578
151 + 171427 = 171578

Showing the first eight; more decompositions exist.
