Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85744, here are decompositions:

11 + 85733 = 85744
41 + 85703 = 85744
53 + 85691 = 85744
83 + 85661 = 85744
101 + 85643 = 85744
137 + 85607 = 85744
167 + 85577 = 85744
173 + 85571 = 85744

Showing the first eight; more decompositions exist.
