Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051894, here are decompositions:

5 + 1051889 = 1051894
47 + 1051847 = 1051894
83 + 1051811 = 1051894
113 + 1051781 = 1051894
131 + 1051763 = 1051894
197 + 1051697 = 1051894
251 + 1051643 = 1051894
293 + 1051601 = 1051894

Showing the first eight; more decompositions exist.
