Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051864, here are decompositions:

17 + 1051847 = 1051864
53 + 1051811 = 1051864
83 + 1051781 = 1051864
101 + 1051763 = 1051864
167 + 1051697 = 1051864
257 + 1051607 = 1051864
263 + 1051601 = 1051864
293 + 1051571 = 1051864

Showing the first eight; more decompositions exist.
