Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38782, here are decompositions:

53 + 38729 = 38782
59 + 38723 = 38782
71 + 38711 = 38782
83 + 38699 = 38782
89 + 38693 = 38782
113 + 38669 = 38782
131 + 38651 = 38782
173 + 38609 = 38782

Showing the first eight; more decompositions exist.
