Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628544, here are decompositions:

101 + 8628443 = 8628544
137 + 8628407 = 8628544
167 + 8628377 = 8628544
191 + 8628353 = 8628544
251 + 8628293 = 8628544
311 + 8628233 = 8628544
383 + 8628161 = 8628544
467 + 8628077 = 8628544

Showing the first eight; more decompositions exist.
