Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722550, here are decompositions:

73 + 8722477 = 8722550
79 + 8722471 = 8722550
103 + 8722447 = 8722550
127 + 8722423 = 8722550
157 + 8722393 = 8722550
211 + 8722339 = 8722550
313 + 8722237 = 8722550
379 + 8722171 = 8722550

Showing the first eight; more decompositions exist.
