Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188970, here are decompositions:

13 + 188957 = 188970
17 + 188953 = 188970
29 + 188941 = 188970
31 + 188939 = 188970
37 + 188933 = 188970
43 + 188927 = 188970
59 + 188911 = 188970
79 + 188891 = 188970

Showing the first eight; more decompositions exist.
