Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105102, here are decompositions:

5 + 105097 = 105102
31 + 105071 = 105102
71 + 105031 = 105102
79 + 105023 = 105102
83 + 105019 = 105102
103 + 104999 = 105102
131 + 104971 = 105102
149 + 104953 = 105102

Showing the first eight; more decompositions exist.
