Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179578, here are decompositions:

5 + 179573 = 179578
29 + 179549 = 179578
59 + 179519 = 179578
107 + 179471 = 179578
137 + 179441 = 179578
149 + 179429 = 179578
167 + 179411 = 179578
197 + 179381 = 179578

Showing the first eight; more decompositions exist.
