Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506542, here are decompositions:

5 + 506537 = 506542
11 + 506531 = 506542
41 + 506501 = 506542
83 + 506459 = 506542
149 + 506393 = 506542
191 + 506351 = 506542
251 + 506291 = 506542
359 + 506183 = 506542

Showing the first eight; more decompositions exist.
