Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71872, here are decompositions:

5 + 71867 = 71872
11 + 71861 = 71872
23 + 71849 = 71872
29 + 71843 = 71872
83 + 71789 = 71872
131 + 71741 = 71872
173 + 71699 = 71872
179 + 71693 = 71872

Showing the first eight; more decompositions exist.
