Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645544, here are decompositions:

53 + 8645491 = 8645544
67 + 8645477 = 8645544
101 + 8645443 = 8645544
113 + 8645431 = 8645544
137 + 8645407 = 8645544
163 + 8645381 = 8645544
191 + 8645353 = 8645544
251 + 8645293 = 8645544

Showing the first eight; more decompositions exist.
