Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104666, here are decompositions:

7 + 104659 = 104666
43 + 104623 = 104666
73 + 104593 = 104666
139 + 104527 = 104666
193 + 104473 = 104666
283 + 104383 = 104666
379 + 104287 = 104666
433 + 104233 = 104666

Showing the first eight; more decompositions exist.
