Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105190, here are decompositions:

17 + 105173 = 105190
23 + 105167 = 105190
47 + 105143 = 105190
53 + 105137 = 105190
83 + 105107 = 105190
167 + 105023 = 105190
191 + 104999 = 105190
257 + 104933 = 105190

Showing the first eight; more decompositions exist.
