Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538330, here are decompositions:

29 + 538301 = 538330
47 + 538283 = 538330
71 + 538259 = 538330
83 + 538247 = 538330
131 + 538199 = 538330
167 + 538163 = 538330
173 + 538157 = 538330
179 + 538151 = 538330

Showing the first eight; more decompositions exist.
