Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105104, here are decompositions:

7 + 105097 = 105104
67 + 105037 = 105104
73 + 105031 = 105104
151 + 104953 = 105104
157 + 104947 = 105104
193 + 104911 = 105104
277 + 104827 = 105104
331 + 104773 = 105104

Showing the first eight; more decompositions exist.
