Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661466, here are decompositions:

5 + 8661461 = 8661466
29 + 8661437 = 8661466
53 + 8661413 = 8661466
59 + 8661407 = 8661466
83 + 8661383 = 8661466
113 + 8661353 = 8661466
227 + 8661239 = 8661466
263 + 8661203 = 8661466

Showing the first eight; more decompositions exist.
