Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661282, here are decompositions:

29 + 8661253 = 8661282
31 + 8661251 = 8661282
41 + 8661241 = 8661282
43 + 8661239 = 8661282
59 + 8661223 = 8661282
79 + 8661203 = 8661282
89 + 8661193 = 8661282
101 + 8661181 = 8661282

Showing the first eight; more decompositions exist.
