Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505370, here are decompositions:

3 + 505367 = 505370
13 + 505357 = 505370
31 + 505339 = 505370
43 + 505327 = 505370
139 + 505231 = 505370
157 + 505213 = 505370
211 + 505159 = 505370
241 + 505129 = 505370

Showing the first eight; more decompositions exist.
