Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104978, here are decompositions:

7 + 104971 = 104978
19 + 104959 = 104978
31 + 104947 = 104978
61 + 104917 = 104978
67 + 104911 = 104978
109 + 104869 = 104978
127 + 104851 = 104978
151 + 104827 = 104978

Showing the first eight; more decompositions exist.
