Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646780, here are decompositions:

29 + 8646751 = 8646780
59 + 8646721 = 8646780
61 + 8646719 = 8646780
71 + 8646709 = 8646780
73 + 8646707 = 8646780
97 + 8646683 = 8646780
113 + 8646667 = 8646780
173 + 8646607 = 8646780

Showing the first eight; more decompositions exist.
