Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105998, here are decompositions:

31 + 105967 = 105998
127 + 105871 = 105998
181 + 105817 = 105998
229 + 105769 = 105998
271 + 105727 = 105998
307 + 105691 = 105998
331 + 105667 = 105998
349 + 105649 = 105998

Showing the first eight; more decompositions exist.
