Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469212, here are decompositions:

5 + 469207 = 469212
19 + 469193 = 469212
43 + 469169 = 469212
59 + 469153 = 469212
71 + 469141 = 469212
113 + 469099 = 469212
181 + 469031 = 469212
229 + 468983 = 469212

Showing the first eight; more decompositions exist.
