Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79870, here are decompositions:

3 + 79867 = 79870
23 + 79847 = 79870
29 + 79841 = 79870
41 + 79829 = 79870
47 + 79823 = 79870
53 + 79817 = 79870
59 + 79811 = 79870
101 + 79769 = 79870

Showing the first eight; more decompositions exist.
