Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737258, here are decompositions:

11 + 8737247 = 8737258
59 + 8737199 = 8737258
191 + 8737067 = 8737258
197 + 8737061 = 8737258
269 + 8736989 = 8737258
347 + 8736911 = 8737258
359 + 8736899 = 8737258
449 + 8736809 = 8737258

Showing the first eight; more decompositions exist.
