Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709146, here are decompositions:

7 + 8709139 = 8709146
13 + 8709133 = 8709146
67 + 8709079 = 8709146
79 + 8709067 = 8709146
139 + 8709007 = 8709146
619 + 8708527 = 8709146
877 + 8708269 = 8709146
1129 + 8708017 = 8709146

Showing the first eight; more decompositions exist.
