Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505140, here are decompositions:

11 + 505129 = 505140
17 + 505123 = 505140
23 + 505117 = 505140
29 + 505111 = 505140
43 + 505097 = 505140
67 + 505073 = 505140
73 + 505067 = 505140
79 + 505061 = 505140

Showing the first eight; more decompositions exist.
