Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85732, here are decompositions:

29 + 85703 = 85732
41 + 85691 = 85732
71 + 85661 = 85732
89 + 85643 = 85732
113 + 85619 = 85732
131 + 85601 = 85732
263 + 85469 = 85732
281 + 85451 = 85732

Showing the first eight; more decompositions exist.
