Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71742, here are decompositions:

23 + 71719 = 71742
29 + 71713 = 71742
31 + 71711 = 71742
43 + 71699 = 71742
71 + 71671 = 71742
79 + 71663 = 71742
109 + 71633 = 71742
149 + 71593 = 71742

Showing the first eight; more decompositions exist.
