Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645554, here are decompositions:

11 + 8645543 = 8645554
173 + 8645381 = 8645554
227 + 8645327 = 8645554
293 + 8645261 = 8645554
311 + 8645243 = 8645554
317 + 8645237 = 8645554
431 + 8645123 = 8645554
563 + 8644991 = 8645554

Showing the first eight; more decompositions exist.
