Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74740, here are decompositions:

11 + 74729 = 74740
23 + 74717 = 74740
41 + 74699 = 74740
53 + 74687 = 74740
131 + 74609 = 74740
167 + 74573 = 74740
173 + 74567 = 74740
179 + 74561 = 74740

Showing the first eight; more decompositions exist.
