Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173578, here are decompositions:

5 + 173573 = 173578
17 + 173561 = 173578
29 + 173549 = 173578
47 + 173531 = 173578
149 + 173429 = 173578
269 + 173309 = 173578
281 + 173297 = 173578
311 + 173267 = 173578

Showing the first eight; more decompositions exist.
