Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051980, here are decompositions:

19 + 1051961 = 1051980
23 + 1051957 = 1051980
31 + 1051949 = 1051980
53 + 1051927 = 1051980
67 + 1051913 = 1051980
101 + 1051879 = 1051980
131 + 1051849 = 1051980
151 + 1051829 = 1051980

Showing the first eight; more decompositions exist.
