Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529180, here are decompositions:

23 + 529157 = 529180
53 + 529127 = 529180
59 + 529121 = 529180
83 + 529097 = 529180
131 + 529049 = 529180
137 + 529043 = 529180
173 + 529007 = 529180
233 + 528947 = 529180

Showing the first eight; more decompositions exist.
