Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529228, here are decompositions:

47 + 529181 = 529228
71 + 529157 = 529228
101 + 529127 = 529228
107 + 529121 = 529228
131 + 529097 = 529228
179 + 529049 = 529228
191 + 529037 = 529228
257 + 528971 = 529228

Showing the first eight; more decompositions exist.
