Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670810, here are decompositions:

19 + 8670791 = 8670810
37 + 8670773 = 8670810
59 + 8670751 = 8670810
67 + 8670743 = 8670810
97 + 8670713 = 8670810
101 + 8670709 = 8670810
107 + 8670703 = 8670810
131 + 8670679 = 8670810

Showing the first eight; more decompositions exist.
