Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505146, here are decompositions:

7 + 505139 = 505146
17 + 505129 = 505146
23 + 505123 = 505146
29 + 505117 = 505146
73 + 505073 = 505146
79 + 505067 = 505146
97 + 505049 = 505146
113 + 505033 = 505146

Showing the first eight; more decompositions exist.
