Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105144, here are decompositions:

7 + 105137 = 105144
37 + 105107 = 105144
47 + 105097 = 105144
73 + 105071 = 105144
107 + 105037 = 105144
113 + 105031 = 105144
157 + 104987 = 105144
173 + 104971 = 105144

Showing the first eight; more decompositions exist.
