Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660404, here are decompositions:

3 + 8660401 = 8660404
17 + 8660387 = 8660404
23 + 8660381 = 8660404
107 + 8660297 = 8660404
113 + 8660291 = 8660404
227 + 8660177 = 8660404
317 + 8660087 = 8660404
353 + 8660051 = 8660404

Showing the first eight; more decompositions exist.
