Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506578, here are decompositions:

5 + 506573 = 506578
41 + 506537 = 506578
47 + 506531 = 506578
71 + 506507 = 506578
197 + 506381 = 506578
227 + 506351 = 506578
239 + 506339 = 506578
251 + 506327 = 506578

Showing the first eight; more decompositions exist.
