Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105054, here are decompositions:

17 + 105037 = 105054
23 + 105031 = 105054
31 + 105023 = 105054
67 + 104987 = 105054
83 + 104971 = 105054
101 + 104953 = 105054
107 + 104947 = 105054
137 + 104917 = 105054

Showing the first eight; more decompositions exist.
