Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506644, here are decompositions:

53 + 506591 = 506644
71 + 506573 = 506644
107 + 506537 = 506644
113 + 506531 = 506644
137 + 506507 = 506644
227 + 506417 = 506644
251 + 506393 = 506644
263 + 506381 = 506644

Showing the first eight; more decompositions exist.
