Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661802, here are decompositions:

3 + 8661799 = 8661802
59 + 8661743 = 8661802
113 + 8661689 = 8661802
173 + 8661629 = 8661802
179 + 8661623 = 8661802
293 + 8661509 = 8661802
311 + 8661491 = 8661802
389 + 8661413 = 8661802

Showing the first eight; more decompositions exist.
