Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051272, here are decompositions:

191 + 1051081 = 1051272
193 + 1051079 = 1051272
263 + 1051009 = 1051272
269 + 1051003 = 1051272
311 + 1050961 = 1051272
359 + 1050913 = 1051272
373 + 1050899 = 1051272
419 + 1050853 = 1051272

Showing the first eight; more decompositions exist.
