Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75724, here are decompositions:

3 + 75721 = 75724
17 + 75707 = 75724
41 + 75683 = 75724
71 + 75653 = 75724
83 + 75641 = 75724
107 + 75617 = 75724
113 + 75611 = 75724
167 + 75557 = 75724

Showing the first eight; more decompositions exist.
