Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179530, here are decompositions:

3 + 179527 = 179530
11 + 179519 = 179530
47 + 179483 = 179530
59 + 179471 = 179530
89 + 179441 = 179530
101 + 179429 = 179530
137 + 179393 = 179530
149 + 179381 = 179530

Showing the first eight; more decompositions exist.
