Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746872, here are decompositions:

11 + 8746861 = 8746872
23 + 8746849 = 8746872
53 + 8746819 = 8746872
59 + 8746813 = 8746872
61 + 8746811 = 8746872
73 + 8746799 = 8746872
139 + 8746733 = 8746872
149 + 8746723 = 8746872

Showing the first eight; more decompositions exist.
