Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722048, here are decompositions:

29 + 8722019 = 8722048
47 + 8722001 = 8722048
59 + 8721989 = 8722048
107 + 8721941 = 8722048
131 + 8721917 = 8722048
197 + 8721851 = 8722048
311 + 8721737 = 8722048
347 + 8721701 = 8722048

Showing the first eight; more decompositions exist.
