Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100986, here are decompositions:

5 + 100981 = 100986
29 + 100957 = 100986
43 + 100943 = 100986
59 + 100927 = 100986
73 + 100913 = 100986
79 + 100907 = 100986
139 + 100847 = 100986
157 + 100829 = 100986

Showing the first eight; more decompositions exist.
