Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178970, here are decompositions:

19 + 178951 = 178970
31 + 178939 = 178970
37 + 178933 = 178970
61 + 178909 = 178970
67 + 178903 = 178970
73 + 178897 = 178970
97 + 178873 = 178970
139 + 178831 = 178970

Showing the first eight; more decompositions exist.
