Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178974, here are decompositions:

23 + 178951 = 178974
41 + 178933 = 178974
43 + 178931 = 178974
53 + 178921 = 178974
67 + 178907 = 178974
71 + 178903 = 178974
97 + 178877 = 178974
101 + 178873 = 178974

Showing the first eight; more decompositions exist.
