Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505190, here are decompositions:

3 + 505187 = 505190
31 + 505159 = 505190
61 + 505129 = 505190
67 + 505123 = 505190
73 + 505117 = 505190
79 + 505111 = 505190
139 + 505051 = 505190
157 + 505033 = 505190

Showing the first eight; more decompositions exist.
