Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506686, here are decompositions:

3 + 506683 = 506686
23 + 506663 = 506686
113 + 506573 = 506686
149 + 506537 = 506686
179 + 506507 = 506686
227 + 506459 = 506686
263 + 506423 = 506686
269 + 506417 = 506686

Showing the first eight; more decompositions exist.
