Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1039920, here are decompositions:

19 + 1039901 = 1039920
23 + 1039897 = 1039920
29 + 1039891 = 1039920
83 + 1039837 = 1039920
97 + 1039823 = 1039920
103 + 1039817 = 1039920
131 + 1039789 = 1039920
151 + 1039769 = 1039920

Showing the first eight; more decompositions exist.
