Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011980, here are decompositions:

7 + 1011973 = 1011980
19 + 1011961 = 1011980
37 + 1011943 = 1011980
43 + 1011937 = 1011980
163 + 1011817 = 1011980
181 + 1011799 = 1011980
283 + 1011697 = 1011980
313 + 1011667 = 1011980

Showing the first eight; more decompositions exist.
