Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7872, here are decompositions:

5 + 7867 = 7872
19 + 7853 = 7872
31 + 7841 = 7872
43 + 7829 = 7872
79 + 7793 = 7872
83 + 7789 = 7872
113 + 7759 = 7872
131 + 7741 = 7872

Showing the first eight; more decompositions exist.
