Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661406, here are decompositions:

23 + 8661383 = 8661406
53 + 8661353 = 8661406
167 + 8661239 = 8661406
233 + 8661173 = 8661406
269 + 8661137 = 8661406
317 + 8661089 = 8661406
359 + 8661047 = 8661406
419 + 8660987 = 8661406

Showing the first eight; more decompositions exist.
