Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681742, here are decompositions:

5 + 8681737 = 8681742
11 + 8681731 = 8681742
73 + 8681669 = 8681742
79 + 8681663 = 8681742
103 + 8681639 = 8681742
163 + 8681579 = 8681742
193 + 8681549 = 8681742
229 + 8681513 = 8681742

Showing the first eight; more decompositions exist.
