Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505240, here are decompositions:

3 + 505237 = 505240
53 + 505187 = 505240
59 + 505181 = 505240
83 + 505157 = 505240
101 + 505139 = 505240
149 + 505091 = 505240
167 + 505073 = 505240
173 + 505067 = 505240

Showing the first eight; more decompositions exist.
