Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105038, here are decompositions:

7 + 105031 = 105038
19 + 105019 = 105038
67 + 104971 = 105038
79 + 104959 = 105038
127 + 104911 = 105038
211 + 104827 = 105038
277 + 104761 = 105038
331 + 104707 = 105038

Showing the first eight; more decompositions exist.
