Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74742, here are decompositions:

11 + 74731 = 74742
13 + 74729 = 74742
23 + 74719 = 74742
29 + 74713 = 74742
43 + 74699 = 74742
89 + 74653 = 74742
131 + 74611 = 74742
181 + 74561 = 74742

Showing the first eight; more decompositions exist.
