Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178170, here are decompositions:

19 + 178151 = 178170
29 + 178141 = 178170
43 + 178127 = 178170
53 + 178117 = 178170
67 + 178103 = 178170
79 + 178091 = 178170
101 + 178069 = 178170
103 + 178067 = 178170

Showing the first eight; more decompositions exist.
