Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173970, here are decompositions:

37 + 173933 = 173970
47 + 173923 = 173970
53 + 173917 = 173970
61 + 173909 = 173970
73 + 173897 = 173970
79 + 173891 = 173970
103 + 173867 = 173970
109 + 173861 = 173970

Showing the first eight; more decompositions exist.
