Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722330, here are decompositions:

47 + 8722283 = 8722330
107 + 8722223 = 8722330
137 + 8722193 = 8722330
233 + 8722097 = 8722330
251 + 8722079 = 8722330
311 + 8722019 = 8722330
389 + 8721941 = 8722330
401 + 8721929 = 8722330

Showing the first eight; more decompositions exist.
