Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85942, here are decompositions:

11 + 85931 = 85942
53 + 85889 = 85942
89 + 85853 = 85942
113 + 85829 = 85942
149 + 85793 = 85942
191 + 85751 = 85942
239 + 85703 = 85942
251 + 85691 = 85942

Showing the first eight; more decompositions exist.
