Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006890, here are decompositions:

7 + 1006883 = 1006890
11 + 1006879 = 1006890
13 + 1006877 = 1006890
29 + 1006861 = 1006890
37 + 1006853 = 1006890
43 + 1006847 = 1006890
107 + 1006783 = 1006890
109 + 1006781 = 1006890

Showing the first eight; more decompositions exist.
