Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1050920, here are decompositions:

7 + 1050913 = 1050920
19 + 1050901 = 1050920
67 + 1050853 = 1050920
103 + 1050817 = 1050920
109 + 1050811 = 1050920
139 + 1050781 = 1050920
151 + 1050769 = 1050920
181 + 1050739 = 1050920

Showing the first eight; more decompositions exist.
