Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105986, here are decompositions:

3 + 105983 = 105986
19 + 105967 = 105986
43 + 105943 = 105986
73 + 105913 = 105986
79 + 105907 = 105986
103 + 105883 = 105986
157 + 105829 = 105986
313 + 105673 = 105986

Showing the first eight; more decompositions exist.
