Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506638, here are decompositions:

29 + 506609 = 506638
47 + 506591 = 506638
101 + 506537 = 506638
107 + 506531 = 506638
131 + 506507 = 506638
137 + 506501 = 506638
179 + 506459 = 506638
257 + 506381 = 506638

Showing the first eight; more decompositions exist.
