Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179872, here are decompositions:

23 + 179849 = 179872
53 + 179819 = 179872
59 + 179813 = 179872
71 + 179801 = 179872
179 + 179693 = 179872
239 + 179633 = 179872
269 + 179603 = 179872
281 + 179591 = 179872

Showing the first eight; more decompositions exist.
