Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47742, here are decompositions:

5 + 47737 = 47742
29 + 47713 = 47742
31 + 47711 = 47742
41 + 47701 = 47742
43 + 47699 = 47742
61 + 47681 = 47742
83 + 47659 = 47742
89 + 47653 = 47742

Showing the first eight; more decompositions exist.
