Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722474, here are decompositions:

3 + 8722471 = 8722474
83 + 8722391 = 8722474
107 + 8722367 = 8722474
113 + 8722361 = 8722474
191 + 8722283 = 8722474
251 + 8722223 = 8722474
263 + 8722211 = 8722474
281 + 8722193 = 8722474

Showing the first eight; more decompositions exist.
