Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104690, here are decompositions:

7 + 104683 = 104690
13 + 104677 = 104690
31 + 104659 = 104690
67 + 104623 = 104690
97 + 104593 = 104690
139 + 104551 = 104690
163 + 104527 = 104690
199 + 104491 = 104690

Showing the first eight; more decompositions exist.
