Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645524, here are decompositions:

47 + 8645477 = 8645524
197 + 8645327 = 8645524
257 + 8645267 = 8645524
263 + 8645261 = 8645524
281 + 8645243 = 8645524
383 + 8645141 = 8645524
401 + 8645123 = 8645524
443 + 8645081 = 8645524

Showing the first eight; more decompositions exist.
