Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746128, here are decompositions:

11 + 8746117 = 8746128
59 + 8746069 = 8746128
137 + 8745991 = 8746128
199 + 8745929 = 8746128
211 + 8745917 = 8746128
239 + 8745889 = 8746128
271 + 8745857 = 8746128
311 + 8745817 = 8746128

Showing the first eight; more decompositions exist.
