Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179072, here are decompositions:

31 + 179041 = 179072
43 + 179029 = 179072
139 + 178933 = 179072
151 + 178921 = 179072
163 + 178909 = 179072
199 + 178873 = 179072
241 + 178831 = 179072
379 + 178693 = 179072

Showing the first eight; more decompositions exist.
