Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105684, here are decompositions:

11 + 105673 = 105684
17 + 105667 = 105684
31 + 105653 = 105684
71 + 105613 = 105684
83 + 105601 = 105684
127 + 105557 = 105684
151 + 105533 = 105684
157 + 105527 = 105684

Showing the first eight; more decompositions exist.
