Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105006, here are decompositions:

7 + 104999 = 105006
19 + 104987 = 105006
47 + 104959 = 105006
53 + 104953 = 105006
59 + 104947 = 105006
73 + 104933 = 105006
89 + 104917 = 105006
127 + 104879 = 105006

Showing the first eight; more decompositions exist.
