Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521182, here are decompositions:

3 + 521179 = 521182
5 + 521177 = 521182
29 + 521153 = 521182
131 + 521051 = 521182
173 + 521009 = 521182
239 + 520943 = 521182
269 + 520913 = 521182
293 + 520889 = 521182

Showing the first eight; more decompositions exist.
