Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104972, here are decompositions:

13 + 104959 = 104972
19 + 104953 = 104972
61 + 104911 = 104972
103 + 104869 = 104972
193 + 104779 = 104972
199 + 104773 = 104972
211 + 104761 = 104972
229 + 104743 = 104972

Showing the first eight; more decompositions exist.
