Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81748, here are decompositions:

11 + 81737 = 81748
41 + 81707 = 81748
47 + 81701 = 81748
59 + 81689 = 81748
71 + 81677 = 81748
101 + 81647 = 81748
137 + 81611 = 81748
179 + 81569 = 81748

Showing the first eight; more decompositions exist.
