Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29742, here are decompositions:

19 + 29723 = 29742
59 + 29683 = 29742
71 + 29671 = 29742
73 + 29669 = 29742
79 + 29663 = 29742
101 + 29641 = 29742
109 + 29633 = 29742
113 + 29629 = 29742

Showing the first eight; more decompositions exist.
