Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051992, here are decompositions:

5 + 1051987 = 1051992
13 + 1051979 = 1051992
31 + 1051961 = 1051992
43 + 1051949 = 1051992
79 + 1051913 = 1051992
89 + 1051903 = 1051992
103 + 1051889 = 1051992
113 + 1051879 = 1051992

Showing the first eight; more decompositions exist.
