Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105158, here are decompositions:

61 + 105097 = 105158
127 + 105031 = 105158
139 + 105019 = 105158
199 + 104959 = 105158
211 + 104947 = 105158
241 + 104917 = 105158
307 + 104851 = 105158
331 + 104827 = 105158

Showing the first eight; more decompositions exist.
