Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538228, here are decompositions:

29 + 538199 = 538228
71 + 538157 = 538228
101 + 538127 = 538228
107 + 538121 = 538228
149 + 538079 = 538228
179 + 538049 = 538228
227 + 538001 = 538228
479 + 537749 = 538228

Showing the first eight; more decompositions exist.
