Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 465140, here are decompositions:

7 + 465133 = 465140
61 + 465079 = 465140
73 + 465067 = 465140
79 + 465061 = 465140
127 + 465013 = 465140
157 + 464983 = 465140
199 + 464941 = 465140
223 + 464917 = 465140

Showing the first eight; more decompositions exist.
