Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68742, here are decompositions:

5 + 68737 = 68742
13 + 68729 = 68742
29 + 68713 = 68742
31 + 68711 = 68742
43 + 68699 = 68742
59 + 68683 = 68742
73 + 68669 = 68742
83 + 68659 = 68742

Showing the first eight; more decompositions exist.
