Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77742, here are decompositions:

11 + 77731 = 77742
19 + 77723 = 77742
23 + 77719 = 77742
29 + 77713 = 77742
31 + 77711 = 77742
43 + 77699 = 77742
53 + 77689 = 77742
61 + 77681 = 77742

Showing the first eight; more decompositions exist.
