Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621454, here are decompositions:

11 + 8621443 = 8621454
41 + 8621413 = 8621454
43 + 8621411 = 8621454
173 + 8621281 = 8621454
211 + 8621243 = 8621454
241 + 8621213 = 8621454
271 + 8621183 = 8621454
307 + 8621147 = 8621454

Showing the first eight; more decompositions exist.
