Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051216, here are decompositions:

59 + 1051157 = 1051216
137 + 1051079 = 1051216
197 + 1051019 = 1051216
239 + 1050977 = 1051216
317 + 1050899 = 1051216
443 + 1050773 = 1051216
479 + 1050737 = 1051216
503 + 1050713 = 1051216

Showing the first eight; more decompositions exist.
