Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661468, here are decompositions:

7 + 8661461 = 8661468
29 + 8661439 = 8661468
31 + 8661437 = 8661468
41 + 8661427 = 8661468
61 + 8661407 = 8661468
157 + 8661311 = 8661468
227 + 8661241 = 8661468
229 + 8661239 = 8661468

Showing the first eight; more decompositions exist.
