Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112872, here are decompositions:

13 + 112859 = 112872
29 + 112843 = 112872
41 + 112831 = 112872
73 + 112799 = 112872
101 + 112771 = 112872
113 + 112759 = 112872
131 + 112741 = 112872
181 + 112691 = 112872

Showing the first eight; more decompositions exist.
