Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63870, here are decompositions:

7 + 63863 = 63870
13 + 63857 = 63870
17 + 63853 = 63870
29 + 63841 = 63870
31 + 63839 = 63870
47 + 63823 = 63870
61 + 63809 = 63870
67 + 63803 = 63870

Showing the first eight; more decompositions exist.
