Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1057212, here are decompositions:

29 + 1057183 = 1057212
31 + 1057181 = 1057212
83 + 1057129 = 1057212
179 + 1057033 = 1057212
193 + 1057019 = 1057212
199 + 1057013 = 1057212
241 + 1056971 = 1057212
263 + 1056949 = 1057212

Showing the first eight; more decompositions exist.
