Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70986, here are decompositions:

5 + 70981 = 70986
7 + 70979 = 70986
17 + 70969 = 70986
29 + 70957 = 70986
37 + 70949 = 70986
67 + 70919 = 70986
73 + 70913 = 70986
107 + 70879 = 70986

Showing the first eight; more decompositions exist.
