Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051138, here are decompositions:

59 + 1051079 = 1051138
131 + 1051007 = 1051138
239 + 1050899 = 1051138
251 + 1050887 = 1051138
401 + 1050737 = 1051138
701 + 1050437 = 1051138
821 + 1050317 = 1051138
857 + 1050281 = 1051138

Showing the first eight; more decompositions exist.
