Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722750, here are decompositions:

11 + 8722739 = 8722750
89 + 8722661 = 8722750
107 + 8722643 = 8722750
137 + 8722613 = 8722750
233 + 8722517 = 8722750
251 + 8722499 = 8722750
359 + 8722391 = 8722750
383 + 8722367 = 8722750

Showing the first eight; more decompositions exist.
