Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75742, here are decompositions:

11 + 75731 = 75742
53 + 75689 = 75742
59 + 75683 = 75742
83 + 75659 = 75742
89 + 75653 = 75742
101 + 75641 = 75742
113 + 75629 = 75742
131 + 75611 = 75742

Showing the first eight; more decompositions exist.
