Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105784, here are decompositions:

17 + 105767 = 105784
23 + 105761 = 105784
83 + 105701 = 105784
101 + 105683 = 105784
131 + 105653 = 105784
227 + 105557 = 105784
251 + 105533 = 105784
257 + 105527 = 105784

Showing the first eight; more decompositions exist.
