Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23742, here are decompositions:

23 + 23719 = 23742
53 + 23689 = 23742
71 + 23671 = 23742
73 + 23669 = 23742
79 + 23663 = 23742
109 + 23633 = 23742
113 + 23629 = 23742
139 + 23603 = 23742

Showing the first eight; more decompositions exist.
