Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947212, here are decompositions:

29 + 947183 = 947212
41 + 947171 = 947212
83 + 947129 = 947212
179 + 947033 = 947212
251 + 946961 = 947212
263 + 946949 = 947212
269 + 946943 = 947212
281 + 946931 = 947212

Showing the first eight; more decompositions exist.
