Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051898, here are decompositions:

19 + 1051879 = 1051898
79 + 1051819 = 1051898
109 + 1051789 = 1051898
139 + 1051759 = 1051898
151 + 1051747 = 1051898
181 + 1051717 = 1051898
277 + 1051621 = 1051898
307 + 1051591 = 1051898

Showing the first eight; more decompositions exist.
