Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505206, here are decompositions:

5 + 505201 = 505206
19 + 505187 = 505206
47 + 505159 = 505206
67 + 505139 = 505206
83 + 505123 = 505206
89 + 505117 = 505206
109 + 505097 = 505206
139 + 505067 = 505206

Showing the first eight; more decompositions exist.
