Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661766, here are decompositions:

23 + 8661743 = 8661766
59 + 8661707 = 8661766
83 + 8661683 = 8661766
137 + 8661629 = 8661766
257 + 8661509 = 8661766
353 + 8661413 = 8661766
359 + 8661407 = 8661766
383 + 8661383 = 8661766

Showing the first eight; more decompositions exist.
