Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009860, here are decompositions:

17 + 1009843 = 1009860
23 + 1009837 = 1009860
41 + 1009819 = 1009860
53 + 1009807 = 1009860
73 + 1009787 = 1009860
79 + 1009781 = 1009860
113 + 1009747 = 1009860
191 + 1009669 = 1009860

Showing the first eight; more decompositions exist.
