Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661322, here are decompositions:

11 + 8661311 = 8661322
41 + 8661281 = 8661322
71 + 8661251 = 8661322
83 + 8661239 = 8661322
149 + 8661173 = 8661322
233 + 8661089 = 8661322
353 + 8660969 = 8661322
389 + 8660933 = 8661322

Showing the first eight; more decompositions exist.
