Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506556, here are decompositions:

5 + 506551 = 506556
19 + 506537 = 506556
23 + 506533 = 506556
97 + 506459 = 506556
107 + 506449 = 506556
139 + 506417 = 506556
163 + 506393 = 506556
199 + 506357 = 506556

Showing the first eight; more decompositions exist.
