Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027930, here are decompositions:

47 + 1027883 = 1027930
89 + 1027841 = 1027930
131 + 1027799 = 1027930
173 + 1027757 = 1027930
179 + 1027751 = 1027930
191 + 1027739 = 1027930
227 + 1027703 = 1027930
251 + 1027679 = 1027930

Showing the first eight; more decompositions exist.
