Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105078, here are decompositions:

7 + 105071 = 105078
41 + 105037 = 105078
47 + 105031 = 105078
59 + 105019 = 105078
79 + 104999 = 105078
107 + 104971 = 105078
131 + 104947 = 105078
167 + 104911 = 105078

Showing the first eight; more decompositions exist.
