Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170740, here are decompositions:

29 + 170711 = 170740
71 + 170669 = 170740
107 + 170633 = 170740
113 + 170627 = 170740
131 + 170609 = 170740
137 + 170603 = 170740
257 + 170483 = 170740
293 + 170447 = 170740

Showing the first eight; more decompositions exist.
