Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657404, here are decompositions:

17 + 8657387 = 8657404
23 + 8657381 = 8657404
47 + 8657357 = 8657404
71 + 8657333 = 8657404
113 + 8657291 = 8657404
167 + 8657237 = 8657404
281 + 8657123 = 8657404
293 + 8657111 = 8657404

Showing the first eight; more decompositions exist.
