Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495740, here are decompositions:

61 + 495679 = 495740
73 + 495667 = 495740
103 + 495637 = 495740
127 + 495613 = 495740
151 + 495589 = 495740
181 + 495559 = 495740
229 + 495511 = 495740
283 + 495457 = 495740

Showing the first eight; more decompositions exist.
