Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051998, here are decompositions:

7 + 1051991 = 1051998
11 + 1051987 = 1051998
19 + 1051979 = 1051998
37 + 1051961 = 1051998
41 + 1051957 = 1051998
71 + 1051927 = 1051998
109 + 1051889 = 1051998
149 + 1051849 = 1051998

Showing the first eight; more decompositions exist.
