Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020972, here are decompositions:

5 + 1020967 = 1020972
11 + 1020961 = 1020972
13 + 1020959 = 1020972
41 + 1020931 = 1020972
59 + 1020913 = 1020972
79 + 1020893 = 1020972
131 + 1020841 = 1020972
149 + 1020823 = 1020972

Showing the first eight; more decompositions exist.
