Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66870, here are decompositions:

7 + 66863 = 66870
17 + 66853 = 66870
19 + 66851 = 66870
29 + 66841 = 66870
61 + 66809 = 66870
73 + 66797 = 66870
79 + 66791 = 66870
107 + 66763 = 66870

Showing the first eight; more decompositions exist.
