Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105902, here are decompositions:

3 + 105899 = 105902
19 + 105883 = 105902
31 + 105871 = 105902
73 + 105829 = 105902
151 + 105751 = 105902
211 + 105691 = 105902
229 + 105673 = 105902
283 + 105619 = 105902

Showing the first eight; more decompositions exist.
