Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101970, here are decompositions:

7 + 101963 = 101970
13 + 101957 = 101970
31 + 101939 = 101970
41 + 101929 = 101970
53 + 101917 = 101970
79 + 101891 = 101970
97 + 101873 = 101970
101 + 101869 = 101970

Showing the first eight; more decompositions exist.
