Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661246, here are decompositions:

5 + 8661241 = 8661246
7 + 8661239 = 8661246
23 + 8661223 = 8661246
29 + 8661217 = 8661246
43 + 8661203 = 8661246
53 + 8661193 = 8661246
73 + 8661173 = 8661246
109 + 8661137 = 8661246

Showing the first eight; more decompositions exist.
