Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051830, here are decompositions:

11 + 1051819 = 1051830
19 + 1051811 = 1051830
41 + 1051789 = 1051830
67 + 1051763 = 1051830
71 + 1051759 = 1051830
83 + 1051747 = 1051830
113 + 1051717 = 1051830
167 + 1051663 = 1051830

Showing the first eight; more decompositions exist.
