Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469188, here are decompositions:

19 + 469169 = 469188
47 + 469141 = 469188
61 + 469127 = 469188
67 + 469121 = 469188
89 + 469099 = 469188
151 + 469037 = 469188
157 + 469031 = 469188
179 + 469009 = 469188

Showing the first eight; more decompositions exist.
