Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505236, here are decompositions:

5 + 505231 = 505236
23 + 505213 = 505236
79 + 505157 = 505236
97 + 505139 = 505236
107 + 505129 = 505236
113 + 505123 = 505236
139 + 505097 = 505236
163 + 505073 = 505236

Showing the first eight; more decompositions exist.
