Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506440, here are decompositions:

17 + 506423 = 506440
23 + 506417 = 506440
47 + 506393 = 506440
59 + 506381 = 506440
83 + 506357 = 506440
89 + 506351 = 506440
101 + 506339 = 506440
107 + 506333 = 506440

Showing the first eight; more decompositions exist.
