Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722300, here are decompositions:

3 + 8722297 = 8722300
17 + 8722283 = 8722300
89 + 8722211 = 8722300
107 + 8722193 = 8722300
113 + 8722187 = 8722300
131 + 8722169 = 8722300
281 + 8722019 = 8722300
311 + 8721989 = 8722300

Showing the first eight; more decompositions exist.
