Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 506138, here are decompositions:

7 + 506131 = 506138
19 + 506119 = 506138
37 + 506101 = 506138
67 + 506071 = 506138
211 + 505927 = 506138
271 + 505867 = 506138
379 + 505759 = 506138
499 + 505639 = 506138

Showing the first eight; more decompositions exist.
