Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505230, here are decompositions:

17 + 505213 = 505230
29 + 505201 = 505230
43 + 505187 = 505230
71 + 505159 = 505230
73 + 505157 = 505230
101 + 505129 = 505230
107 + 505123 = 505230
113 + 505117 = 505230

Showing the first eight; more decompositions exist.
