Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85738, here are decompositions:

5 + 85733 = 85738
47 + 85691 = 85738
71 + 85667 = 85738
131 + 85607 = 85738
137 + 85601 = 85738
167 + 85571 = 85738
251 + 85487 = 85738
269 + 85469 = 85738

Showing the first eight; more decompositions exist.
