Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 176872, here are decompositions:

23 + 176849 = 176872
53 + 176819 = 176872
83 + 176789 = 176872
131 + 176741 = 176872
173 + 176699 = 176872
263 + 176609 = 176872
281 + 176591 = 176872
383 + 176489 = 176872

Showing the first eight; more decompositions exist.
