Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506656, here are decompositions:

47 + 506609 = 506656
83 + 506573 = 506656
149 + 506507 = 506656
197 + 506459 = 506656
233 + 506423 = 506656
239 + 506417 = 506656
263 + 506393 = 506656
317 + 506339 = 506656

Showing the first eight; more decompositions exist.
