Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051878, here are decompositions:

29 + 1051849 = 1051878
31 + 1051847 = 1051878
59 + 1051819 = 1051878
67 + 1051811 = 1051878
89 + 1051789 = 1051878
97 + 1051781 = 1051878
131 + 1051747 = 1051878
181 + 1051697 = 1051878

Showing the first eight; more decompositions exist.
